Masochistic Meme Dump

I HAVE INVENTED A MEME:

That's right, my own meme from my own brainjuice -- you heard it first here at capture_the_art, rejoice!

1.) Name one of my characters (past, present, pending, etc.) and ONE major detail that changed in their past, and I will do my best to tell you about this AU version of them! Details could be things like changes to family relation dynamics, what they studied in school or where they went (or what House for HP characters), switching from "good" to "bad" or vice versa, etc. etc. Characters here!

NOT MY OWN BUT I'LL DO IT TOO:

2.) Give me the name of one of my characters, and I will tell you three reasons why it would be terrible to date them, have sex with them, and/or be in a long-term relationship with them. Characters here!

...So yeah.
