“I don’t think I can do this.”
Dean stops dead in his tracks outside the library and listens through the half-open door. His half-formed idea of finding Cas to ask him for dinner suggestions (the rest of the group can deal with whatever the newly former-angel wants to eat) evaporates at the sound of Cas’s voice.
He knows that eavesdroppers rarely hear well of themselves, but Cas has been acting distant for two weeks now and Dean has had it. If listening in on a private conversation between Cas and whoever else will help Dean get Cas back to the too-close, intensely staring bastard he usually is, Dean’s more than willing.
“Of course you can.” That’s Charlie’s voice, chipper and encouraging.
“Just pretend, ok?” Sam says supportively. “It’ll be good practice.”
‘Practice for what’, Dean has no idea. He hears Cas sigh, resigned, and his curiosity ratchets up another notch.
“It won’t help,” Cas says. He pauses. “I shouldn’t-”
“You should,” Charlie interjects immediately, like this is the beginning of a very old argument. “Good things will happen, I promise.”
“Yeah,” Sam says, and Dean can almost picture the encouraging nod that goes along with the word. “Look, I know Dean better than anyone, and I’m absolutely sure he’d want to know.”
