A/N E/O Challenge: Space
Spoilers for Season 7, especially the first two episodes.
Happy birthday, FallenAngel218 and Madd Alles. Sorry this wasn't Sam getting the better of Dean, but I think it qualifies for brotherly angst.

Under the Microscope

by CFEditor

Sam played with his napkin nervously and Dean stared.

"What's wrong?" he asked.

Sam threw the napkin at Dean. "Stop that!"

"Stop what?"

"Stop analyzing everything I do!" He ruffled his hair nervously.

"It's not just napkin origami," said Dean. "There's the hair twirling..."

"I swear, since you found out Lucie's in my head, you watch every move I make," Sam snapped. "If I stand, sit, twitch my nose..."

"I didn't mean..." said Dean.

"I'm like an ant under a damn microscope. Just give me some space, man!" He escaped to the bathroom for a welcome break from his brother.
