Dean visibly jerked at that. He wasn't sure why now, of all times, they'd decided this was a good time to get into this. But then that was how they were. They caused problems when things were quiet. Maybe before Sam dove into the Cage would've been more poetic, he supposed, but this was more like them. A random act of insanity that could ruin them forever.
"Of course you liked it, I'm an awesome kisser," Dean joked, casting an anxious smile Sam's way. "But... you know, this whole Amelia thing and... I don't know what I want, but I know what I don't want is for you to go runnin' at me like a bull when you're this fresh out of things with her."
Standing in front of Sam, he wondered if his whole 'both feet in or both feet out' speech had sank in deeper than he planned. After a moment, he leaned up to kiss him, just enough to make a point. Against everything he stood for, he was... maybe a little open to something.
