Hey there,
I was hoping someone could remember a fic for me. I believe it was a trilogy, and it was titled with parts from the old Humpty Dumpty nursery rhyme. "All the kings horses and all the kings men, couldn't put Humpty back together again". Yeah. Ummm, but yes, it's a flash back fic where Sam and Dean are hunting man made monkey like things, and one of them is clamped on Sam's leg so they go to pastor Jim's. Sam has to go to the hospital and he flashes back to when he was paralyzed by werewolves as a teenager. I remember Sam was really clingy to Dean cause of a venom in the monkey's saliva, and that John eventually shows up, so this is obviously first season/pre-series.
