"I am not putting her clothes on!" Dean said. However, he was already rummanging through Ruby's dresser and pulling on a pair of pants and a shirt. Sans underwear. Because he did NOT care if this was her body .. or well, it wasn't even her own body. Whatever. He didn't care. He wasn't wearing Ruby's underwear.
"I'm going to guess by your reaction that either you're not Sam or you've finally come to your senses Sammy." Dean managed to pull up a smirk from somewhere, even though he knew with good reasoning that the latter wasn't the case.
With a sigh, his hands went up as if to rub over his head but he paused. He wasn't touching this body anymore more than he really and truly had to. "I'm decent!" He called out to the door.
