"Hey," Sam glanced over his shoulder at Dean. The look was fleeting, and he was back to looking for something or other in a cabinet. He didn't even care what he was looking for, he just wanted the distraction. He didn't know how to relate to Dean anymore, he didn't know what to say to him. He didn't particularly care, but somewhere deep inside of him seeing the pain he caused his brother hurt him too. It was the one thing he sort of felt, if he admitted he felt anything at all.
Sam didn't know precisely what was wrong with him. He knew something wasn't right, something was wrong in the eyes of everyone around him. He didn't feel the same way, he was infinitely stronger, he didn't need to eat as much, didn't need to sleep at all. Everything changed after he woke up in the middle of a field, after his stint in Lucifer's cage. He didn't generally think much beyond that, except when he was face to face with Dean.
Why had he agreed to meet his brother? The fact they had been assigned separate rooms afforded them some space, and Sam could easily avoid Dean for days at a time. He liked it that way. "Looks like there's some pie in the fridge. Didn't look what kind it is."
