[Of course he's the one that's responsible for Kurt's pain. Even if Mystique is a bad person in Kurt's timeline, it's still hard to be okay with the thought of her dying-- turning into a stone statue. He's trained with Raven now and looks up to her as a mentor and instructor, a senior X-Man, so hearing any version of her suffer like that sucks.

Then there's the added revelation of Erik dying too.

Scott's feelings towards Magneto is sort of complex, but he doesn't want him dead. Not after he helped stop Apocalypse in the end and helped repair the mansion. It's not like he was the one that fully set human-mutant relations back. Yeah he worked for Apocalypse, but then he'd have to get mad at Ororo too in that case.

He still has all this anger and the mutant's already dead in his world. Sometimes, Scott doesn't know where to direct it. So, directly, almost in a clipped tone:]

So he's a bastard in every universe. [.....] If you're wondering how we defeated him, it took the combined effort of me and several other mutants. Mostly Jean though.

[She really is powerful, isn't she? But also kind, funny, and cute. Those feelings and thoughts haven't faded since returning to Aldrip, it's just he doesn't want to romantically be with her anymore. He'll always have her side though. No matter what.

He wonders what sort of power she unleashed that day. She hasn't been able to fully replicate it since then.]
