Barry doesn't take Merlin's extended hand. Which doesn't really seem to phase the man much at all since a second later he's walking away from him. Barry stares after him for a long moment before running after him to catch up. He's still a special, even if he's a dangerous one.

"Hey," Barry says as he catches up to him. He steps in front of his path. "I don't know what you're trying to do, but there's no point in lying here. The Computer knows who you are."

His eyes narrow as he looks Merlin over. Is it him, or does he look younger? "Who is Captain Jack Harkness?"
