Seems very different from Aaron post AvX, where wolverine, thor get to be phoenix and he uses a lot without Jean
I think Aaron had some plan for Jean, It's not normal Jean being name dropped on MU without mutants involvement and even before phoenix get involved on the storyIn the current Avengers run Jean got two mentions (once by Captain America when talking about needing a telepath and another time a narration box said Jean was hunched over in Atlantis having fiery visions (this was when she would have been in Atlantis during X-men Red). I felt then that Aaron may have had plans for Jean (or it was just misdirection) but plans probably changed.
I was hoping Jean was going to have some sort of connection to cave woman Phoenix (who has red eyes and green hair and telepathy) but that remains to be seen, and may be unlikely though we can always speculate. As much as I personally love Jean as Phoenix, I also love her as just Jean Grey an omega telepath. I wish we could have the best of both worlds like we did in the Morrison run (jean being a grown up omega mutant who sometimes channels the Phoenix). In Here Comes Tomorrow she plugged into the phoenix power through her crown chakra (so we I infer that she plugs into it because of her omega level telepathy).
But Hickman really made his plans change, as krakoa is position as Mutant supremacy so being on avengers is out of the cards.
Aaron talked that Hickman mutants may clash with marvel universe later, then maybe we will get Jean involvement with avengers and the phoenix
