It's funny how Marvel's two most iconic redheads, both linked to Marvel's two most popular characters, have never met in-universe. Even though their fandoms have quite a bit of overlap (re-reading Renew Your Vows and the letter pages has a fan say that Jean and MJ are his two favs). Had Jean been included in New Avengers like Bendis wanted, then we could probably have seen some moments between the two.
Throwback to when Jean and MJ were both on the best dressed list.
