ALL-NEW X-MEN has been a great ride so far. We've seen the original X-Men taken from the past and brought into their future, our present. It's been a tough ordeal for many of them in seeing how much has changed. In particular, Jean Grey has had a lot to deal with.
Back in issue #5, the current day Beast, who is responsible for bringing them forward, allowed Jean to enter his mind. He felt she needed to know what had happened and this let her see what her future will be.
When time travel is involved, there's always the question of how much of your future should you know. Knowing too much could obviously cause problems but those precautions have clearly been thrown out the door. It makes sense that the X-Men should know what has happened between their time and where they are now. We even saw the potential danger when young Cyclops ran off and encountered Mystique, not knowing what a threat she was to the X-Men.
In the current issue (which is reviewed HERE), there is an encounter with Havok and his Uncanny Avengers. There was some confusion and trepidation upon seeing Scarlet Witch on a team of Avengers since they only know her as part of Magneto's Brotherhood of Evil Mutants.
Jean decided to peer into Wanda's mind and was horrified to discover her role in the mutant decimation. Her reaction lead to her striking out and a little battle resulted.
What seems odd about all this is that Jean wasn't aware of this before. None of the young X-Men were. Again, it could be a matter of how much do they need to know but with Jean's powers developing earlier than they were supposed to, there's always the threat of them getting out of control. Also, how did she not pick up on this part of history when peering into Hank's mind?
It's possible when Hank shared his memories with Jean, the focus was just on her life. Because we're not telepaths, there's no telling how the mind would work on the psychic plane. When Jean entered Hank's mind, she may have only had access to the memories that involved her.
We have seen Jean struggle with the urge to simply read the minds of others. How could she not come across those of the worst moment in Mutant History? Hank was there during M-Day. He was on hand when the X-Men and Avengers met to discuss what to do with Wanda before the world was turned upside down and then she uttered those three devastating words.
The important thing is the young X-Men need to know what has happened (will happen for them) if they are to remain in the present. It's unclear how long their stay will last. We know there's an upcoming arc (Battle of the Atom) where another group of X-Men, from the current day's future, arrives to try to make it clear the young X-Men need to return to their time.
But there has been so much that has happened in the X-Men and Marvel Universe. They need to brush up on the history/future in order to know who their allies are and who cannot be trusted.
One would think the X-Men would have detailed computer files describing everything that has happened. But with a telepath, it wouldn't be required that they sit and read all the data. They could easily have someone's recollection and knowledge shared with the others. It could be a problem with them knowing too much. But being in their present could already be causing problems and they need to know what has happened and who they can and cannot trust. It's surprising and irresponsible to think that Hank or Kitty haven't thought about giving the young X-Men a full history lesson on their future.
There's no point in hiding things from them if they're going to be here for a while. They've already discovered more than they should know. But for their safety and that of the X-Men, they need to know the facts.
