Sam knew something was wrong the moment he entered the caffeè and saw his brother. His face looked… Odd. Even when the girl slapped him, Sam knew something was wrong. Dean might be a one night stand guy, but he never forget the girls he had just hooked up with a night before.
The things got worse when Dean asked him, with the stupidest expression of ignorance ever "Who's Dean?" Sam called immediately Rowena and Cas. Rowena for the spell, Cas for another… Mission.
Sam had sticked post-it notes everywhere. When Cas walked into the motel room, Sam stopped him.
"Why you stop me from entering, Sam? Is Dean okay?"
Sam smirked as he sticked the note on Cas' forehead. "You're ready now" He entered the room with Cas, grinning like an idiot.
"Dean, this is Cas"
Dean's face perked up from TV and approached the angel. He had a post-it note too. "Boy-friend? I've a boyfriend?" He turned at Sam. Castiel looked at Sam too. "Sam why are you-"
"Shush!" Sam pinched the angel's lips to forbid him from speaking. "Keep an eye on him, will you?"
Castiel nods as Sam leaves. Dean looked at the angel with interest.
"So… Angel huh? Do you have wings and a helo?" Dean laid on the bed seductively, smirking flirtatiously. Cas blushed.
"Uhm… I don't.. Have a helo, Dean", he answers and sits next to the hunter. "How you feeling?"
"I feel awesome!", Dean chuckles. "So… You're my boyfriend, what boyfriends do?"
Cas blushes even more. Fortunately, Rowena choosed that moment to come in, raising an eyebrow at both of them.
While Sam was taking care of the case and Rowena helped him with the spell, Dean grew more and more fond of Cas. He couldn't remember him, of course but he wanted to touch him. They were laid together in Dean's bed at nights, Dean sleeping at Cas' chest while Cas was holding him close, watching over him.
