This won't make sense unless you've seen the X-men 3 movie. If you haven't seen the movie yet but want to, then avert your eyes quickly from the following! Throughout the last battle I kept thinking that Rogue would jump out from behind Pheonix and stop her. Considering the destruction she was causing this would probably have been impossible though. Still, I couldn't help being disappointed at Rogue's choice. My brother and I discussed alternatives and came up with this. Admittably, it has some flaws.
I liked the X-men movies because of their political dimension, but the creators seem reluctant to let any character stay dead.
