This choice doesn't affect the main story or Hogwarts Legacy's ending, so it really is just up to the player to decide which character they'd rather go with.
This is what happens based on your choice. If you turn Sebastian in, he will be expelled from Hogwarts and you will not be able to interact with him again in the game. This means that, if he hasn't already taught you the Unforgivable Curses, now he never will. He will be taken to the Ministry of Magic to face justice.
The character has an interesting story path in Hogwarts Legacy revolving around his family and past, so you would be missing out on a compelling narrative if you turn him in. If you do turn Sebastian in, it will lock out additional content that could extend your time in the Wizarding World's darker side.
Turning in Sebastian will result in his being expelled from Hogwarts. As a result, he won't be available in quests at the end of the game and won't be in the epilogue. Instead, Ominis Gaunt will take Sebastian Sallow's place in the “In the Shadow of Friendship” quest line.
Neither telling Natty the truth nor lying affects your relationship with Natty and the outcome of the quest The Girl from Uagadou. Both dialogue options also lead to short conversations too, since Natty doesn't have any new knowledge to offer regarding Ancient Magic.
Hogwarts Legacy: Visit Hogsmeade with Natsai or Sebastian - Both choices and outcomes
Should I tell Natty and Sebastian the truth?
In the end, players should opt for whichever option they feel fits their character best, as there is no real difference between withholding or telling Sebastian the truth in Hogwarts Legacy. Editor's Note: Harry Potter creator J.K. Rowling has been accused of transphobia by those in the LGBTQ+ community.
He's always going to have a showdown with his uncle after he goes too far down the dark magic rabbit hole, and eventually he uses the killing curse on him. None of this changes, the only difference is that you can choose whether or not to turn Sebastian in for killing his uncle or not.
Sebastian is very much a “the path to hell is paved with good intentions” type of character. The more people tell him that nothing good can come of this path the more he doubles down on it. No one can doubt his love for his sister or his passion but that very passion is leading him down a very dark path.
Should I side with Sebastian or Ominous in Hogwarts Legacy?
Regardless of which dialogue option the player chooses, it won't affect the outcome of the situation, because Sebastian will always end up taking the relic. If the player encourages him to proceed with his plan, he'll unsurprisingly agree and take the relic.
Choosing whether to turn Sebastian in or not is arguably the biggest decision players will have to make during their Hogwarts Legacy playthrough. Not only will it affect how the In the Shadow of Friendship quest plays out, but it will also have a notable impact on the game's final cutscene.
Can you get the killing curse if you turn Sebastian in?
So long as you don't turn Sebastian in to Azkaban, you're able to learn the Unforgivable Curses from him at any time after refusing to learn them earlier in the game. Depends. If you don't, turn him in at the end of the quest line then he will teach them to you, but if you turn him in he's gone for good.
If you answer “I intend to keep it contained here” then you'll trigger the Good Ending. You can also add that you intend to keep it a secret forever, or that you'll eventually share this knowledge with some people close to you, but this second choice doesn't have any affect.
Overall, the plot was a failure. Anne Sallow was never cured, Solomon Sallow was senselessly murdered, and it was unlikely that Sebastian Sallow ever recovered from what he had done.
As noted above, only the Good and Evil endings constitute different outcomes for the conclusion of Hogwarts Legacy. Thankfully, both endings are very easy to achieve as they hinge on a single choice you have to make near the end of the game's penultimate quest "The Final Repository", right before the final boss fight.
Can you get banned for cheating in Hogwarts Legacy?
Sorry, I should've clarified: they have the right to ban you for using mods, even in an offline single player game. Some offline single player games, at least, do detect if you're using mods.
In the game, you can essentially just pick whatever house you want, so the choice is always in your hands, despite that's not how it works in the lore. And to answer the first question, there is no “best” house outside of personal preference and history within the universe.
Wondering what difference wand flexibility makes in Hogwarts Legacy? Don't worry - it doesn't actually change anything and is little more than a bit of flavor to make you feel involved. No matter what core, wood, or flexibility you choose, it won't do anything in the game once you start playing.
If you're having second thoughts on whether or not to learn Avada Kedavra, you can learn it from Sebastian later on if you make the certain story choices.
Visiting Azkaban in Hogwarts Legacy is only an option for players who chose a particular House at the start of the game, and it is only a very brief and linear visit, but it's still exciting to see and walk around such a storied locale, even briefly.
