"Hey, Dean, pass the salt," Sam asked casually at dinner. Shit, Dean thought, act natural.
"Get it yourself, Rapunzel," he snapped. Look, he doesn't suspect a thing. Just keep playing it cool and your demon brother won't figure out that you're a demon.
Sam gave an offended huff and reached past his brother to grab the salt, "So how'd you come back from the dead? I was about to summon Crowley you'd been gone so long."
Dammit, dammit. Don't let him find out, "It was one of the angels."
"Since when did angels bring you back? And since when did you not touch a cheeseburger?" Dean quickly grabbed the burger and scarfed it down.
"I'm fine, Sam. Why don't we just enjoy the fact that somebody brought me back?" Sam nodded hesitantly and turned his attention back to his own food.
It wasn't that Dean didn't want to tell his brother what'd really happened, he just couldn't bring himself to. Sam had already been through enough without finding out that his brother had been turned into one of the things they hunted. Although, this situation was making things difficult. He'd already accidentally burned himself twice this morning and Sam was starting to wonder why there was always sulfur everywhere. Dammit this was hard.
He remembered what it'd been like when he was human: food and sex and feelings. Being a demon now meant that he didn't need any of those things anymore, which was great, but keeping up appearances for Sammy was starting to give him a headache. If his brother found out about his little secret, there would definitely be trouble.
