That wasn't Jean, though. It was Phoenix-as-Jean. The real Jean was recovering from injuries in a cocoon at the bottom of Jamaica Bay. Reconned before being published or not, that's the story. X-men history.
This latest "Scott's a dick" thing isn't the only reason Cyclops is disliked by a lot of X-men fans. He's been a dick for quite some time. I actually feel for the character. How is going to feel when, after the Phoenix Force leaves him, he recalls what he did? Remember, Scott insisted the PF be allowed to come to earth unopposed by the X-men, despite Tony Stark's stupid weapon that split the entity (I still find this event very bothersome).
Not that anything could have stopped the Phoenix, anyway.
I don't think Cyclops is the one in the wrong here. He only wanted Hope to have the Pheonix power. At some point, he realizes or feels that she is not able to handle the responsibility or power and decides to take it on himself. This is where this story falls short. What was he doing with the power? What was his plan? We won't know because the Avengers and Xavier jumped in to say no way Jose. Again....no discussion. Only, we are here to see that Hope doesn't become Phoenix. The question should have been. What do you intend to do with Hope?
