Hi everyone! Looking for a few things, hoping for your help just like all previous times you wonderful folk you :)

1) Specific: I feel like I've looked everywhere and it's driving me crazy. What I remember: early season 8 (before any Trials, Dean still treats Sam like crap). At some point somehow Sam leaves, Dean thinks he's decided to bail for good and doesn't even think to look for him. Amelia seeks Dean out. Turns out Sam made a deal with the Alpha Vampire for Dean's return from Purgatory, and as per that deal every few months Sam had to go to the Alpha, who proceeded to drink from him (I think) and just generally use Sam as a punching bag because there's something about his pain being "addictive" or some such??? Of course a rescue happens, I think Benny was also involved in it? Any ideas? Anybody?

2) General: don't really care how, don't really care why, but Sam is the proud/bewildered owner of a hellhound puppy or several. I just want all the shmoopy, feel-good, rot-your-teeth-out-of-your-head-sweet fic of Sam cuddling hellhound puppies and giving them tummy rubs and just generally being a completely awesome dog-loving dork and the pups snuggling all over him and being all drool-in-your-face ridiculously adorable for Sam, but don't let that fool you, because they're still hellhounds, and they're not shy about letting anyone who so much as breathes funny around Sam know this. Bonus points for Dean being leery of them at first - "they're Hellhounds, Sam!" - but slowly warming up to them (they're dang useful on a hunt! ...and, okay, kinda cute in a feral kind of way) and sneaking them treats UWU

3) As a sort of side-order on the above, Sam as any kind of pet owner, really, whether mundane or supernatural.

Please and thank you: no animal deaths. No evil Sam.
