So they've been in the present for 21 issues. They're now part of Adult Cyke's team. They've met the Avengers, all teams and have experienced BOTA. Young Cyke even met his older brother. And they seem like they enjoy having these long talks.
But they STILL only know one side of the whole story. There are 2 sides to this coin, and right now, the O5 apart from Warren think adult Cyclops is insane. He is to blame for everything that went wrong in their lives. So why have they not had a long talk with him yet ? Get his version of the whole story.
Why has young Jean not given adult Cyke the full brain-scan like she did on Beast ? ( Nope the thoughts she read from when they first met him were about what was on his mind at that time, not his/her full life's story from his perspective like she got from Hank). Why didn't Cyke ask his older self what really happened to his dad and Sinister ?
Having the O5 run around with just half ( and extremely biased, it's friggin Adult Beast and Wolverine's "truths" lol ) the truth when all they need to do is look right under their noses for the whole story, seems like just a lazy excuse for Bendis to keep the drama and "teen angst" flowing.
My 2 cents...
