Let's not forget how many times they had mentioned "Alexis" before she arrived, these guys are not exactly subtle about their intentions. I could imagine the CW being desperate enough to keep the buzz going even if that means they have to reveal a spoiler (but without specific storylines). NK is not going to risk anything, of course. We all assume that they will manage to get Cristal out of the burning barn, get her to the hospital and then...a coma or plastic surgery storyline. But she could die in the fire, and maybe that would be better. The last thing we need is a departure "Pam Ewing" style.
