Also, I feel like Gen X Vol 2 took place in some AU dimension. Other than Jubilee keeping her powers and Monet getting herself back (both of which could have been done with the current era) I don’t think a single thing from that run actually stuck. So much so, it’s honestly hard for me to count any of those kids as Gen X. It had no lasting impact on any of those characters tbh. Even Eye-Boy who (aside from Quire) was probably the biggest character in the students before the run happened.
So going back to the original question, I don’t anything those kids do reflects on Jubilee unless specifically stated.
