So I finally got around to reading it.
I disagree entirely, I thoroughly enjoyed it. I thought the last few pages were rather tragic and well written. The splicing of the three different storylines happening at once, converging at one point, it's easy to see why what happens is overlooked by the other two events.
It's easy to say Kitty is out of character when she's acting differently, because fans of Kitty still expect her to be a young girl. However, she's has to "cowboy up", as the out-of-date-expression goes, and be a big girl now. "Firing" Husk was a necessity and she has been given a major task in being "headmistress" of that school. She has a whole new series of tough decisions, but we've seen her stand her ground to their enemies and even the avengers or their own fellow-mutants, repeatedly within this title. If you ask me? This was completely in character, in terms of the evolution of the character. She's developing into a tough cookie, and I'm going to say Aaron has a good grip on that. As for the Pep-talk with Charles? I suppose.
I said this with something else recently, forget what, but it's as unbelievable as you want it to be. Do you genuinely believe that Charles would know what is happening to him, do you think he is "gradfather" or "sage" character in Logan's Hero's Journey, aware of the path before and behind the hero and giving him last-moment, fateful advice that he can either take or not? Do you feel Xavier is the most powerful mutant telepath on Earth?
I do. And because I believe those two things, that was a totally understandable assertion for Aaron to have that final message to Logan.
Those're my 2 cents.
