My first exposure to Jean (in a sense) along with the X-Men was Uncanny #175, which to me encapsulates everything the X-Men are about. I liked Dark Phoenix's look and how she turned Colossus into a pretzel. Then some time later I got more caught up with the Gold team, so I've always been accustomed to her presence to where I took it for granted. With that in mind I've thought that if not for the 50th anniversary then maybe it'll wait until a 90's Marvel fanboy gets creative control. I have been going over some X-Factor collections and she played a pretty interesting role so there's that to go through... 

I was especially surprised with Cypher's return and rather liked that one of his first actions upon his return was to use body language-reading similar to a previous Batgirl to best all of his teammates. The sense I got from that particular return was that he kind of slipped through the cracks in the midst of a larger event. I guess a Jean return would have to be a way bigger deal
