Yes! Teen Jean came in not long after AvX and had to deal with a lot of the fallout. The Avengers came and tried to force the teens to go back to their original timeline and Jean read their minds and learned a lot about their bad shit (particularly, Wanda's M-Day shenanigans) and lashed out at them. There's also a lot of sentiment on the Avengers that hold her accountable for the Phoenix shit which...she hasn't done. And Teen Jean has enough guilt over shit she hasn't done!
