So I had posted this before but I didn't get any reply and since I'm really really dying to re-read it, I thought I'd try again.
I think I read it on fanfiction.net. It's set in Season 2, post BUABS. Gordon manages to convince Steve Wandell's daughter that Sam is evil and together they attempt to kill Sam. After she finds out that Sam was posessed, she feels guilty and decides to help the Winchesters nab Gordon. I think towards the end of the fic, she kisses Sam on the cheek.
Any ideas which fic it is? Thank you guys in advance! You guys are awesome.
FOUND! It's
Vengeance by
IHeartSam. Thanks to the amazing
