Dean does want to talk except for the part where he really doesn't because he doesn't know what to say. He's bad at talking, especially about things like feelings. Crap.

He gives the body a good kick on his way out, just to turn it around and slow it down a little further (he's got no idea if it'll work but that isn't stopping him from trying.). Outside, he yanks the back of the Impala open, stowing his machete and gesturing for Castiel to do the same to his arsenal. Lucky for Cas, Dean's not so unobservant that he doesn't see the fidgeting--and since when does Castiel fidget?

"You gonna get in or not?" Dean slides into the driver's seat, stretching across the seats to shove the passenger side door open.
