Am I the only person who thinks that is bull? I don't seem to recall Rogue ever being timid. Admittedly she was timid about having to crawl to her enemies(the x-ment) begging for forgiveness for what she did to Ms. Marvel- I would be too. A little humility helps but timid, I don't recall that ever in Rogue's personality. This seems to me to be a way to justify how useless Rogue was in the first movie. This just proves to me what I've always thought, Rogue was better off with Mystique at first. She pushed Rogue to not withdraw from use of her powers where the X-Men treat is like a plague. Sure, it has obvious not so nice reprocussions as compared to Jean Grey happily reading people's minds. I really wish Marie would join Mystique for awhile in the movieverse. How about let's see her get to use her power in a really neat defense like everyone else's power gets to in the previews.
If I can choose this story it would be ideal for Rogue to move on during or at the end of this movie to train with Mystique for awhile. ;p
