Barry? Brook paused at the admittance before eventually realizing that Usopp was saying that was his name. By the way Brook took his meaning, it sounded as though Usopp was having to play along somehow. It was obviously true that claiming to be a pirate usually didn't end too well, particularly when it came to the World Government. Brook hadn't been too careful in telling others there of his profession, and while it hadn't ended badly yet, he was still stuck there. Usopp, or Barry meanwhile was visiting from outside of this place.

Was he on the run maybe?

"Ah... so it's Barry now? I suppose there could be worse names!" he joked with a laugh. Of all the names Usopp could have chosen, Brook would have thought he'd pick a more imposing name. Barry didn't sound too impressive from where he was sitting but then again, neither did Brook.
