Castiel's face feels surprisingly soft under his fist, perhaps subconsciously expecting all that angel strength to flood back into him. It doesn't, though, and he goes for another haymaker only to have those hands wrap around his wrists. Castiel's body is surprisingly strong without the angel mojo, but Dean knows how to fight, and now he's running on purely adrenaline. He surges his weight forward, pushing Castiel off balance and down the hallway. "Let go of me, you fuck," he snarls, eyes hard. "Unless you're gonna give me Michael as an imaginary friend, let go of me, of I fucking swear, I will put you in the goddamn hospital."
