One of the most pivotal decisions in Hogwarts Legacy comes early in the game but carries weight far beyond its moment. When you uncover Sebastian Sallow’s dark path and dangerous secrets, you’ll face a choice that splits the entire narrative: turn him in to the authorities, or keep his secret and try to pull him back from the brink. This decision cascades through the remainder of your playthrough, changing storylines, questlines, combat mechanics, and how characters interact with you going forward. For completionists and role-players alike, the choice between turning Sebastian in or not defines not just Sebastian’s fate but your character’s moral stance in the wizarding world. Here’s what you need to know about both paths, and which one might be right for your specific playthrough.
Key Takeaways
- The Sebastian Sallow decision in Hogwarts Legacy determines his character fate, your moral stance, and access to exclusive questlines and combat mechanics that define your entire playthrough.
- Turning Sebastian in removes him from the game permanently, locks you out of his complete questline, and damages your reputation with Slytherin students, while keeping his secret allows his full character arc and redemption opportunity.
- Sebastian is a sympathetic character manipulated by his uncle and driven by desperation to save his mother, making the moral choice between redemption and justice equally valid from both roleplay and story perspectives.
- Not reporting Sebastian to authorities keeps him available as a powerful combat ally with devastating dark magic spells, providing genuine gameplay advantages in late-game duels and difficulty scenarios.
- Completionists should not turn Sebastian in during their first playthrough to experience his full narrative scope, then use New Game Plus to explore the alternative path on a subsequent run.
The Sebastian Sallow Storyline Explained
Who Is Sebastian Sallow
Sebastian Sallow starts out as one of the most compelling characters in Hogwarts Legacy. He’s a Slytherin student with a tortured backstory, his mother is in an inferi state (essentially undead), and his uncle Solomon is a dark wizard who’s actively pushing him toward dark magic as the only “cure” for his mother’s condition. Over the course of his questline, Sebastian becomes increasingly isolated, desperate, and morally compromised. He’s not a straightforward villain: he’s a kid being manipulated by his family and genuinely believes he’s pursuing an impossible goal (saving his mother) through the only means available to him.
What makes Sebastian unique is how the game frames him as a victim of circumstances and manipulation. He’s talented, charming when he wants to be, and genuinely confused about whether his choices are right or wrong. That moral ambiguity is what makes the turn-him-in-or-not decision so agonizing for players.
The Dark Path Choices Leading To The Decision
Sebastian doesn’t just wake up evil. His descent into dark magic is a series of incremental choices and circumstances that pile up over the course of your friendship. During his questline, you’ll encounter several branching moments:
- Defensive vs. Aggressive Dueling: Early in the questline, Sebastian’s attitudes shift based on whether you encourage his interest in dark magic or discourage it. But, unlike some other relationship-based games, your choices here don’t fully prevent his descent.
- The Undercroft Meetings: Sebastian gains access to the Undercroft (the secret dueling space), where he practices increasingly dark spells. He introduces you to dark magic, including curses that cause pain without physical wounds.
- Solomon’s Influence: Sebastian’s uncle escalates the pressure, revealing more of his plans and pulling Sebastian deeper into the dark magic philosophy.
- The Ranrok Connection: By the third act, Sebastian becomes entangled with Ranrok and the goblin rebellion, seeing them as allies who share his desire for change. This is the point of no return: Sebastian is no longer just a confused student but an active participant in a conspiracy against Hogwarts.
The decision to turn him in happens after you discover his involvement with Ranrok. At that point, he’s genuinely dangerous, not just to himself, but to the school. He’s committed to dark magic, aligned with enemies of Hogwarts, and seemingly unwilling to step back. That’s what makes the choice so morally complex: is he still redeemable, or has he crossed a line?
What Happens If You Turn Sebastian In
Immediate Consequences At Hogwarts
If you choose to report Sebastian to Professor Fig or other school authorities, the consequences are immediate and tangible. Sebastian is arrested and removed from Hogwarts. The Undercroft is seized. Other students you’ve befriended through Sebastian (particularly those in Slytherin) become noticeably cold toward you. Word spreads through the school that you betrayed a fellow student, and your reputation, especially among Slytherin students, takes a hit.
The atmosphere shifts noticeably. Sebastian’s friends, even those who didn’t share his dark interests, resent you for the betrayal. In Slytherin common room conversations and random NPC dialogue, you’ll overhear resentment directed at the player character. It’s not gamebreaking, but it’s a genuine social consequence.
Sebastian’s Fate And Storyline Ending
When you turn Sebastian in, his questline ends definitively. He’s expelled from Hogwarts or imprisoned (the game’s narrative is slightly vague here, but the intent is clear: he’s gone from the school). You don’t see him again. His mother remains in her inferi state with no magical cure ever discovered. Solomon Sallow presumably continues his dark magic operations without his nephew.
This ending carries a grim finality. Sebastian’s arc concludes not with redemption or even his own choice, but with external judgment and removal. There’s no second act for him, no chance to prove he could change. Many players find this ending unsatisfying specifically because it removes agency from Sebastian’s story, he doesn’t get to choose his path: it’s chosen for him.
Impact On Your House Points And Reputation
Turning Sebastian in generates significant House point penalties, your House loses points for the betrayal. The exact number varies depending on your House affiliation (Slytherin loses more than other Houses for losing a student, while other Houses still lose points for the betrayal itself).
Your reputation takes a hit among Slytherin students but improves slightly with Gryffindor students and the school administration. Authority figures respect that you reported a genuine threat. But, in a school where Slytherin pride runs deep, you’ve made enemies. If you’re a Slytherin player, this choice creates an interesting roleplay tension: you’ve sided with the school over your own House.
What Happens If You Don’t Turn Sebastian In
Keeping Sebastian’s Secret And Remaining Friends
If you choose not to report Sebastian, you’re essentially endorsing his agency. You’re saying, “I believe you can change. I’m going to trust you and stand by you.” This unlocks a very different ending to his questline, one where Sebastian himself makes the final choice about his direction.
Staying silent means Sebastian continues at Hogwarts for the remainder of the game. You maintain your friendship with him. He remains available for questlines, duels, and collaboration throughout the later game. The dynamic shifts, though, there’s a tacit understanding between you both that you’re aware of his involvement with dark magic and Ranrok, but you’re choosing not to report him. That creates a different kind of tension.
Sebastian’s Alternative Ending
This is the major appeal of not turning Sebastian in. In this path, Sebastian’s character arc concludes differently. During the final confrontation (which varies slightly depending on your relationship status), Sebastian is given the opportunity to make his own choice about his future. With your influence and support throughout the game, there’s a possibility Sebastian can step back from dark magic and Ranrok.
The “good” version of this ending shows Sebastian genuinely reflecting on his choices, acknowledging his mistakes, and choosing a different path forward, not because he was forced by authorities, but because someone believed in him enough to let him choose. It’s redemptive without being saccharine. Sebastian’s final fate is less clear-cut than the “turned in” path (which is intentional, the game respects player agency over narrative closure), but the implication is that he’s given a genuine second chance.
Critically, keeping Sebastian’s secret means his mother’s situation remains unresolved, much like in the other path. Dark magic offers no real solution to inferi curse, and this reality becomes part of Sebastian’s growth.
Availability As A Questline Ally
If you keep Sebastian’s secret, he remains available as a questline ally for the remainder of the game. He can still duel alongside you, provide backup in combat scenarios, and his questline can be fully completed. This is mechanically significant: Sebastian is a talented duelist, and having him available as an ally provides genuine combat support. His dark magic spells (like Crucio and Avada Kedavra if you’ve progressed his questline that far) are devastating in combat, and his presence can turn difficult fights in your favor.
Comparing Both Choices: Gameplay And Story Differences
Questline Outcomes And Exclusive Content
The two paths offer fundamentally different questline completion experiences. If you turn Sebastian in, his questline ends early, and you miss access to his later quests and the full scope of his character arc. You won’t see his final confrontation, his moment of reflection, or the resolution of his relationship with Ranrok. That content is simply gone.
If you don’t turn him in, you access the complete Sebastian questline. This includes additional quests, deeper exploration of his relationship with Solomon, confrontations with Ranrok, and the aforementioned climactic moment where his character is fully defined. For completionists, this is the only way to experience the full narrative scope of one of the game’s most developed characters.
Beyond Sebastian himself, keeping him as an ally unlocks unique dialogue and interaction opportunities throughout the second half of the game. NPCs reference your loyalty to Sebastian, other Slytherin students acknowledge your choice, and the narrative acknowledges that you’ve made a controversial decision.
Character Relationships And Friendship Dynamics
The two choices significantly alter how other characters perceive and interact with you. When you turn Sebastian in, Slytherin-aligned students view you with suspicion or outright hostility. Ominis Gaunt (Sebastian’s closest friend) is disappointed and confrontational about your betrayal. The trust you’ve built with various Slytherin characters diminishes.
Conversely, not turning Sebastian in strengthens your bond with him and improves your standing among Slytherin students who respect loyalty over judgment. Ominis remains conflicted, he knows Sebastian is dangerous, but he respects that you’re trying to help rather than punish. This doesn’t mean every character approves (Professor Fig, for example, has moral concerns), but the social dynamics within the student body shift in your favor among your House.
Other core characters have nuanced reactions to both choices. Poppy Sweeting, Sebastian’s friend from the Hippogriff rescue side questline, responds differently depending on your stance. Professor Black and other Slytherin staff have subtle reactions based on House loyalty.
Combat Mechanics And Ally Differences
This is where the gameplay differences become concrete. When you turn Sebastian in, you lose access to him as a combat ally. For the remainder of the game, your ally pool excludes Sebastian entirely. You’ll rely on other companions like Ominis, Leander, or Imelda for backup in duels and combat.
Sebastian as a combat ally is notably effective. He specializes in dark magic spells, which are often devastating. His DPS (damage per second) is solid, and his dark curses apply status effects that can disable enemies. If you’ve progressed his questline significantly, he’ll have access to Crucio (Cruciatus Curse), which forces enemies to stagger and take increased damage. For late-game duels on higher difficulties, having Sebastian’s damage output available is genuinely valuable.
Also, dueling with Sebastian offers unique dialogue and interactions. The game acknowledges and responds to the fact that you’re fighting alongside a dark wizard. Some enemies react with surprise or fear. The narrative weaves the mechanical choice into the storytelling.
Moral Implications: Which Choice Feels Right
The Redemption Argument
The “don’t turn him in” argument rests on the premise that redemption is possible and that people deserve second chances, even when they’ve made terrible choices. Sebastian is a victim of generational trauma, family manipulation, and impossible circumstances. His uncle Solomon literally lied to him about the nature of dark magic and its healing properties, and his mother’s condition gave him emotional leverage that no child should bear.
From this perspective, turning him in abandons a student who needed help, support, and guidance. It’s the easy choice, remove the problem rather than solve it. Sebastian’s choice to pursue dark magic came from desperation and manipulation, not inherent evil. A true mentor figure believes in his potential to change and provides the support structure for that change to happen.
This argument is particularly compelling because the game itself frames Sebastian as sympathetic. His questline is designed to make players understand his motivations, even if they disagree with his methods. The narrative repeatedly emphasizes that he’s trying to save his mother, not achieve power for its own sake. From a story perspective, not turning him in respects the game’s careful construction of his character as a tragedy rather than a villain.
The Justice And School Safety Argument
The counterargument is equally valid: by the time you discover his involvement with Ranrok, Sebastian is no longer just a misguided student, he’s a genuine threat to Hogwarts and everyone in it. Ranrok’s rebellion involves actual violence, theft, and conspiracy. Sebastian’s involvement makes him complicit in actions that endanger lives.
From this perspective, loyalty to a friend doesn’t outweigh your responsibility to the broader school community. If you stayed silent about Sebastian’s involvement and Ranrok’s plans later caused casualties or damage, would you bear responsibility for that? Turning him in is the difficult but moral choice because it prioritizes safety and justice over personal loyalty.
There’s also the matter of agency and consequence. Sebastian chose dark magic. Sebastian chose to work with Ranrok. Protecting him from consequences is enabling his continued descent, not saving him. True redemption might require him to face what he’s done, accept responsibility, and rebuild from that point. Letting him off the hook doesn’t heal him: it avoids the problem.
Beyond Sebastian, there’s a school-wide safety consideration. Other students might follow his example. Other dark wizards might recruit more students. By allowing Sebastian to remain at Hogwarts after his involvement with Ranrok is revealed, you’re implicitly saying that dark magic conspiracy is tolerable within the school’s structure. That sets a dangerous precedent.
Which Choice Should You Make: Recommendations By Playstyle
For Players Seeking Every Storyline And Secret
If you’re a completionist determined to experience every quest and piece of content Hogwarts Legacy offers, you must not turn Sebastian in during your first playthrough. Turning him in ends his questline permanently, locking you out of content you can only access by keeping him in the game. You lose the ability to fully explore his character arc, complete his final questlines, and witness his climactic character moment.
This doesn’t mean you can’t experience the “turn him in” path, you absolutely can, using the New Game Plus feature mentioned later in this guide. But in a single playthrough, locking yourself out of half of Sebastian’s content is objectively counterproductive to the completionist goal. Keep him in the game, complete every Sebastian-related quest, and then start a new run if you want to explore the alternative.
For Roleplayers And Moral Purists
Roleplayers should consider what their character actually believes. If you’re playing a character who’s genuinely trying to be a good person and protect the school, turning Sebastian in might align perfectly with that moral framework. Your character is making the hard choice, the brave choice, the unpopular choice, that’s compelling roleplay.
Conversely, if you’re playing a character who values loyalty, friendship, and redemption above institutional authority, keeping Sebastian’s secret is the roleplay choice that makes sense. Your character is saying, “I trust in people’s capacity to change, and I’m willing to take risks to prove that belief.”
The key is internal consistency. Don’t make the choice because you think one is objectively “better”, make it because it aligns with who your character is. That’s what makes the roleplay meaningful. The game supports both choices equally (mechanically and narratively), so neither is mechanically “wrong.”
For moral purists specifically, understand that neither choice is perfectly clean. Turning him in is justice but abandonment. Keeping his secret is loyalty but enabling. The game intentionally avoids giving you a “correct” moral answer. Your purist stance should grapple with that complexity rather than demanding clarity the game refuses to provide.
For Completionists Aiming To Experience Both
If you want to see both paths and make an well-informed choice on a subsequent playthrough, the strategy is straightforward: don’t turn Sebastian in on your first run. Experience his full questline and ending. Get a sense of his character arc when he’s given the chance to choose his own path. Then, on a second playthrough (using New Game Plus or a fresh start), choose the opposite. This approach gives you full context for both decisions and lets you experience the complete game across multiple runs.
Many players find this two-playthrough approach the most satisfying because it respects both the game’s narrative depth and the genuine weight of the decision. You’re not agonizing endlessly about which choice is “right”, you’re planning to see both paths and then deciding which resonates more with you personally.
New Game Plus And Multiple Playthroughs
Testing Both Choices Across Different Runs
Hogwarts Legacy supports New Game Plus, which lets you start a fresh campaign while carrying over select progression elements. This feature is specifically useful for decisions like the Sebastian choice because it lets you test both paths without restarting from scratch or abandoning hours of progress.
When you start New Game Plus, you retain certain statistics and upgrades (depending on the version and update), but the story resets entirely. This means you can replay the Sebastian questline and make the opposite choice. The game acknowledges this replayability through various hints in the narrative and NPC dialogue, subtly suggesting that different playthroughs can yield different outcomes.
Many serious Hogwarts Legacy players approach the game with the intention of doing two playthroughs specifically to experience both major branching paths: one where they turn Sebastian in, and one where they don’t. This isn’t necessary for “100% completion” in a strict sense (the game doesn’t gate achievements on mutually exclusive choices), but it’s how experienced players ensure they’ve seen the full scope of what the narrative offers.
The campaign length makes multiple playthroughs feasible but not trivial. A full playthrough of Hogwarts Legacy takes roughly 40-60 hours depending on side content engagement. New Game Plus slightly accelerates the experience since you’re already familiar with quests and locations, but you’re still committing significant time. That’s why the choice between doing one or two playthroughs is genuinely strategic, it depends on how much you value seeing all narrative paths versus moving on to other games.
Conclusion
The Sebastian Sallow decision is one of Hogwarts Legacy’s most carefully constructed moral choices precisely because it has no objectively correct answer. Turning him in is justice and school safety, but it abandons a student who needed redemption. Keeping his secret is loyalty and faith in potential, but it enables someone genuinely involved in dangerous conspiracy.
For gameplay purposes, not turning Sebastian in gives you access to more questlines, more ally options, and a fuller experience of his character arc. If you’re planning only one playthrough, this is the pragmatic choice. If you’re comfortable doing multiple runs, through New Game Plus or fresh starts, you can experience both paths and let the narrative complexity sit with you rather than forcing a clean resolution.
Eventually, your choice should reflect what your character believes and what feels true to your playthrough’s story. The game respects both decisions equally, which is rare and valuable. Embrace the weight of the choice rather than seeing it as a puzzle with a hidden “best” solution. That’s where the real depth of the complete Hogwarts Legacy experience becomes apparent.
Whichever path you choose on your first run, remember that you can play Hogwarts Legacy with friends and share your decision-making process with your gaming community. These conversations about character arcs and moral complexity are part of what makes story-driven games meaningful. Don’t let indecision paralyze you, pick a path that feels right, see it through, and come back for the alternative whenever you’re ready.
