So, this was the prompt:
Set between the first and second X-Men movies. Something happens, and for whatever reason Erik and Charles become young again, looking just like they did in First Class. They also only remember everything that happened up to the age they are, so they don't know that they are now enemies.
Anyways, I'd like for the rest of the X-Men to try and desperately find a cure and being weirded out at the fact that their now young Professor is being all lovey-dovey with the enemy. I'd also love it if some of the X-Men notice just how pretty young!Charles looks, and once Erik realize how many people are wanting to get into his man's pants, he get extremely possessive.
Bonus points for Charles getting drunk at some point and flirting (in that adorable geeky way) with anything that moves, much to Erik's disdain.
I DIDN'T REALLY WRITE ANYTHING LIKE THAT AT ALL, I got carried away with my own little plot instead.
