[As soon as the water hits her, Abaddon lets out a screech and staggers backward. She's fully ready to stab Sam with the knife she squirreled away from Castiel, but at that point Sam's punch knocks her to the ground, and next thing any of them know, those cuffs are out.

Dean's eyes widen and dart to the symbols etched in on the shackles, and Abaddon lets out a frustrated noise which sounds particularly strange in Dean's rough tone.]

You can take me in, but you're going to have a hard time getting me to give up your brother now that I have him.

[Castiel, meanwhile, has been left to stand there dumbfounded as he's still processing the lingering feeling of Dean's tongue having been in his mouth. He rubs his palm over his lips and then glares down at the trapped demon.]

We have our ways. [And Castiel expects that Dean's going to fight this as hard as he possibly can. Not that it's possible for a vessel to expel a demon with willpower alone, but it helps to know he's in there fighting tooth and nail.

Abaddon's words from before had probably just been more lies, but Castiel can't forget them so easily. He glances toward Sam.] We'll take them back to the car?
