Sam and Daniel were perfect for each other. They were the same man in two different bodies, both bookish and sensitive at heart, but soldiers through years of necessity. Dean watched them huddled over an obscure Enochian text and thought it was a shame, that Sam found the one person in the whole universe (or whole other universe) who was perfect for him, and the man was helping them find a way to be permanently separated. Sam was helping Daniel right back, of course.

They'd fallen on each other's problems like starving men on a Thanksgiving buffet. Daniel accepted the existence of angels, demons, and alternate universes with aplomb. Sam accepted the existence of aliens, time travel, and interstellar travel with aplomb. Dean was a bit more skeptical about Daniel's story, about how he and his friends had been trapped in an alternate timeline with no way to fix it and certain danger on the way, but Daniel was a damn good translator, knew a couple dozen languages, including some Dean was sure were made up, and he had Sam were making headway on the question of reversing the spell that had brought them to this frightening reality where their lives were a TV show. And Sam – Sam had always adored science and math, so he'd dived into the problem of time travel and alternate timelines with enthusiasm. He and Daniel spent ridiculous amounts of time at the public library and the university library Daniel had access to, reading textbooks and history books and positing theories.

Dean saw the way Sam smiled at Daniel, the way his face lit up while Daniel waxed enthusiastic about a specific point of Enochian grammar. Sam had smiled at Jessica Moore like that once. Dean had always only seen those smiles from a distance. Up close, Dean understood why Sam had stayed away like he had for all those years. Sam was happy.

Dean saw the way Daniel looked at Sam when Sam wasn't looking, the fondness and the longing and something else, something a little more shadowed and a little more sad than seemed fair. If the man's tale was true, though, then he'd been through hell, even died and come back a few times. He'd fit right in with the Winchesters and Team Free Will. Sadness was on the table all around for the three of them.

Dean saw the way Daniel and Sam lit up at exactly the same moment, when both of them cried, "I've got it!"

And then they realized what solving the problem meant, and their smiles dissolved, and then Sam was reaching up to pull off Daniel's glasses and set them aside, and Daniel was gazing at Sam like a desert wanderer at an oasis, and Dean slipped out of the room to let them say their goodbyes.
