As Laura goes, I don't think there was anything necessarily forced or unnatural about HOW she ended up in the book, though I'd certainly like to see it eventually shown how she went from that rescue/medevac chopper at the end of Arena, to being tortured by Purifiers which led to her wandering Miami in a temporary-amnesiac state for Kitty and the O5 to rescue her in the first place. The only thing "unnatural" about her in ANXM so far seems to be Bendis trying to excuse how badly he writes her voice as being the result of some sort of PTSD personality shift brought on by Murderworld (y'know, because it's not like she wasn't already classic PTSD before that whole mess started in the first place or anything).
