So, Channing Tatum expounds his Gambittiness in the movie, revealing whatever back story that they wish to go with, and after the credits roll......
You find Remy musing the interesting events that just happened, deciding if he wishes to go with the devil or the angel metaphorically pulling at his shoulders, and then comes a figure in green, with short bi-colored hair (as in still working with the Brotherhood days) who leans against the doorway and smiles.
"Well hey there, Sugar. I got a proposition for your," she smiles, "particular talents."
Bam! That's it! Cuz who is better to woo Gambit than the "bad" Rogue pre-X-Men. Both of their speckled pasts have a lot to do with bringing them together in the future, and honestly, I'm tired of seeing whiny, angsty Rogue (No offense Anna, you are otherwise awesome. Too bad you hadn't already channeled your True Blood when you were first playing her, cuz that would have been AWESOME!! Instead, they mixed you with Jubilee and, well, there were a lot of issues). Oh well, HOPE for the future!!
