You reminded me of Alchemy and the students recently killed in Gold.
It is perfectly possible to live a life outside the X-mens even if it is not shown but once you end up having some connection with them your life will never be the same at some time or another this connection will cause some incident or even the death.In fact this comic could be a differential showing the life of mutants outside of school or following their lives outside the X-mens but for the time being has not gone into this much or the reason to have students in different classes.
Changing the subject understand that writers want to tell their own stories but I really would like plots to be finished before jumping to next. Not long ago Roxanne kissed Jubilee and tried to approach her romantically and no matter how understood that some feel uncomfortable with it at least would rather see Jubilee moving away from Bling than ignore everything that happened.Although admit that Chamber and Jubilee makes more sense.
