Spoiler!

I doubt they'll pull a time travel reset at the end of this, it would really cut the knees out from under the show. If they just reset it, what's the point? Also if this is part of the MCU multiverse I have to wonder if they'll retcon the MCU time travel rules into it.

Spoiler!

I think Magneto is alive, but they may play the long game with it. One of the comic arcs they're borrowing from is 'E is for Extinction', where Magneto is seemingly killed in a Sentinel massacre on Genosha. Later a new character called Xorn joins the team, but is eventually revealed to be Magneto in disguise when he goes crazy and attacks New York (then is almost immediately retconned into not being Magneto after all, because comics). But the point is, in the comics, this took like 40 issues to play out. And remember, they had already written season 2 and were working on season 3 when the showrunner was fired.
