mmm argh this is the kind of thing I don't generally love in comics? Honestly thinking about the ethics of time travel* and superpowered mutants just gives me so much anxiety. Ahhhh

but it was a good payoff to something that had been building up the last few arcs.

* I like All-New X-Men because that book seems to have a much more whimsical approach to time travel so I feel less stressed about it.
