But I'm finding it difficult to find much to say about that. Maybe this is because I'm coming at it out of order - I've written many of the surrounding entries weeks ago and now I'm coming in and filling in a hole. But it's more that the elements I was expecting to see first hand have already happened. That Rogue-Ms. Marvel grudge has always been backstory, never news.
Spider-Woman (Jessica Drew) finds Carol Danvers (Ms. Marvel and former Avenger) being dumped into the San Francisco Bay on the first page, figures out who she is and what's happened to her with Xavier's help, and contacts the Avengers. During this, we get a bunch of flashbacks that rewrite another story (Avengers #200). It then moves to a large fight between the Avengers and Mystique's Brotherhood of Evil Mutants (with the line-up from Days of Future Past), but now with Rogue. The Avengers defeat them, they run away, yadda yadda.
In the final segment of the annual ("chapter 5"), the Avengers visit Carol, who is recuperating at the X-Mansion. And she really gives them what for, for abandoning her in her time of need in #200. Which is completely fair - having briefly read Avengers #200, I can agree with the general consensus that what was done to her in that was abominable. What I wasn't expecting was that this is being treated here as a far more life-destroying incident than the mere wiping of her identity by Rogue, because it was a betrayal. For all that Rogue has broken Carol, it's the Avengers simply letting Marcus do what he wants with her, without considering the possibility of mind control, that matters. And this is absolutely not a problem inserted into an originally innocent story. It's there in any reading of #200. It's no wonder that Bendis has Carol champion Jessica Jones's cause after her similar ordeal at the hands of the Purple Man. I can see Carol reconciling with Rogue eventually, even at this point. It's more of a wonder that Carol ever signs up with the Avengers again.
