Supernatural/White Collar AU
In which Sam and Dean go looking for the Devil’s other son, who currently goes by the name Neal Caffrey.

“You’ve got guts, walking in here with fake badges. They might have got by Peter but they’re not good enough to fool me. You’re not FBI, so who are you? What do you want with me?”

Sam and Dean exchanged glances. Caffrey seemed amused by the whole affair. Why this guy didn’t rat them out the second he saw the forgeries, who knew. But he was listening, so that was the hard part over. Maybe.

“We know who you are. Who you really are. That Neal Caffrey is just another alias,” Dean said. “It’s ingenious, really. We were impressed when we finally found you. Using your god-given talent to get by, hiding in plain sight. Sorry, Devil-given.”

The smile vanished from Caffrey’s face. “That’s an interesting theory.”

“We’re hunters,” Sam said. “We know who your father is. And we need your help to stop him.”

The room got colder. Dean shivered involutarily.

“I think you ought to be going now,” Caffrey said. “My friends outside might want to talk with you once I tell them you’re committing a felony right here at FBI headquarters.”

“Fine. We’ll leave. But other hunters know you’re here,” Sam said, carefully placing his card on the table. “And they won’t be as friendly as us.”
