Rating: PG13 (language)

Disclaimer: Supernatural and Buffy are not mine. No way. Not at all.

Summary: Dean can feel Sam slipping away from him.

A/N: This is in the same 'verse as Pup but can be read alone.

-----------------------------------
Dean hates Spike.

He hates his jacket. He hates his boots. He hates his stupid fucking hair. He hates the way Spike talks to Sammy and touches Sammy and, if Dean was crazy enough to ask if they were fucking, he’d sure as fuck hate that too.

‘Mine, bitch!’ Dean says with a hand on Sammy’s shoulder. ‘Mine. You can’t take him.’

But Spike smiles like a beast and his tongue runs across his teeth. “Hey, pup,” he says, casually. “You’ll never guess what I found.”

And Sammy looks up with open curiosity because Spike brings the good stuff, the ancient books and the sharp knives and all the other shit Sammy loves.

Spike’s smile changes as he looks at Dean’s little brother. Its indulgence, like Sammy’s his new pet and ‘isn’t he just fucking cute’ and it makes Dean grind his teeth loud enough that the asshole has got to fucking hear him.

Spike doesn’t let on though. Instead, he leads the way toward his crap-bucket of a car (Dean hates that too) and Sammy follows, bounding along after Spike and slipping easily out of Dean’s grasp.

Dean wishes it was daylight so he could watch the fucker burn.
