I read it as more as Kwannon being angry at the entire situation & ignoring a much needed conversation. Betsy even tried to approach her & talk only for Kwannon to say it wasn't needed. Avoidance 101. I know both Hill & Tini have both said to different degrees that eventually they'll be a discussion. However in the importance of this whole X books relaunch, I can see it happening a long while in should both books last. Or in a annual sometimes next year.
I like the fact that Hill as revealed that Kwannon's not even her real name. I'm getting the idea she was some sort of child assassin/solider a la X-23 or even Cable in some ways.
I like that Betsy wanted to say something but Kwannon's like "Nope, nothing to talk about." I think it shows growth for Betsy, who wanted to avoid the body during her solo mini.
I want both of their books to succeed. My only complaint about Fallen Angels was the art. Some pages are beautiful, others are meh. Makes me wonder is that a styling choice or just being rushed. Excalibur's got beautiful colors & shadows, almost what I'd expect from a trippy magical tale. If Fallens more about psychological & personal issues I could see the art fitting it & growing on me.
