Dean gave Sam a slight nod as he grabbed another pair of cuffs. "Kick me and I'll break your kneecaps with a crowbar. That'll be like six to eight months in recovery after the surgery. If we let you live."
He crouched down and cuffed the man's ankles together, standing up and sliding his Colt pistol from the back of his jeans, tapping it against Calhoun's jaw. "Now, you're gonna let my little brother put you in the trunk of our car, and if you start screamin' I'm gonna stick a bullet somewhere not so fun, you hear me?"
Backing away from him, Dean moved to hold the trunk open for Sam, flashing Selina a quick grin that was strained and savage rather than the fond looks he normally gave her.
