Raylan doesn't pull away aside from that small shift, not wanting to create space between them but he also won't stop Ben if wants to pull away. He didn't.

"I-" No, he still didn't quite understand. "Who?"

Nineteen? Part of him felt a little dirty somehow - he was a 43 year old man. He knew Ben was young - no. Presented as young but Raylan somehow both felt like a cradle robber and a robbed cradle himself. It didn't matter. Not really, not once they were outside legality and he knew that Ben's ID claimed older than 19.
