It's good to hear her say that, actually. One of my major issues with Rogue and Magneto was just how hypocritical Rogue was in how she treated Gambit for his crimes and how she treated (or didn't treat) Magneto for his far worse crimes.
I do think she was being too nice to Carey though, but maybe that was just her trying to be tactful and professional. She said that nobody could have really tackled the issue. Well, if nobody could have tackled the issue, then it didn't make sense for her to get together with Magneto! Either that or Rogue was just downright not being a cool person.
On a different note, I read the wedding issue again. In the first group shot at the bar, is that Cable or Magneto behind Beast? I'd put the picture up but I'm very lazy. If it is Magneto then it hilariously seems as though he's looking mournfully over at Rogue and Gambit. I might just imagine that it is him.
