Blood is Thicker Than Water by Whilom
He sucks it down because he needs it, because if he wants to live he has no other choice. He has to pace himself, remind himself to breathe in between desperate gulps and swallows, or he'll choke and it'll all come up again. There's enough water in the world for you, Dean, he thinks, but lets one last mouthful flood his aching throat before he caps the bottle and gets down to business.
He needs to find Sam.

He needs to find Dean.
That's the second thing on his agenda—Get back to Dean, how could you just leave him—but right now his whole body aches and doesn't seem to fit him and his veins feel like they're dry, like not enough is in them. Then Ruby comes with her pale arms and sharp knife and Sam has to pace himself, remind himself of why he's doing this and how he'll (finally) save Dean with this power he's drinking. He sucks it down because he needs it, because if he wants to live he has no other choice.
