“Relationship” in Hogwarts Legacy means Sebastian Sallow’s friendship and story quests—not a romance path. His questline includes a pivotal opportunity to learn Avada Kedavra and a separate decision about whether to turn him in. The choices affect spell access and the version of his final quest, but the available sources do not establish every possible later route for learning the curse.

How Sebastian’s relationship questline works

Sebastian’s story unfolds across a series of relationship quests. Game8’s guide lists 13 quests in the questline and identifies In the Shadow of Friendship as the final Sebastian quest; that count is Game8’s, not an official figure published by the game’s creators. Game8’s Sebastian questline guide.

The choices to focus on are distinct: whether to accept Sebastian’s offer to teach Avada Kedavra, and whether to turn him in. They address spell access and the final quest’s version, respectively.

When can you learn Avada Kedavra?

The relevant opportunity comes during In the Shadow of the Relic. The walkthrough lists Avada Kedavra as a quest reward and describes a conversation afterward in which you can discuss learning the Killing Curse. IGN’s walkthrough for In the Shadow of the Relic.

Should you turn Sebastian in?

This is a role-play decision, not a choice with one objectively best answer. The supported consequence is that it changes which version of Sebastian’s final relationship quest takes place. A guide describes In the Shadow of Friendship as having versions depending on whether Sebastian was turned in; another says he still appears in the final quest if you do not turn him in.

Choose based on how you want your character to respond to Sebastian’s actions. The available information supports a change to the final quest and who is present there; it does not establish broader ending consequences.
