Castiel got to his feet slowly next to Dean. His hand reached into his coat and produced the milk bottle now filled with holy water from the kitchen.

Demon-Dean grinned a little at the stand-off. "You wanna stay in there? Be my guest. Sam's hangin' around here somewhere. We'll go find him. Hell, he and I are more blood than you two are these days anyway."
