I think that's probably why Mary-Kate dyed her hair :D But nowadays I feel like it's getting easier telling them apart because MK has like a pointier face... but I heard that they both were sick and that's why they stay out of the spotlight.

Yeah, it was a HP fic. I think Jace is supposed to be Draco and Clary is Ginny and Simon is Harry. No idea where the others are though. But maybe google can help :D

Yeah, the 50 Shades Fanfic really was funny because I felt like the writing wasn't that good but yeah, if 50 Shades got published maybe there's still hope for me :D
There are a few Twilight Fan Fictions that got published and I once read one (it's called Wallbanger if you want to google it :D) and only after a few chapters I felt llike I read it before and then googled it and found out that it was a Fic once :D
