Though the anger didn't leave his face, there was a flicker of calculation as Mello cross-referenced the names with the information from the message board. He couldn't recall any details about Sai, but he'd made a point to remember Usopp's claimed access to to gunpowder and saltpeter. Unfortunately, that knowledge wouldn't help him now...he'd already claimed to be lost, and anything except ignorance would look suspicious.

Although Mello would have preferred to keep his room number to himself, this situation overruled his natural suspicion and he didn't want to be caught in more than one lie at a time. "Room M3," he said, but his voice was stubborn and nothing in his face revealed that it had been a compromise. "And my name's Mello. This is my first night here, so you'll understand if I'm a little cautious too."

He wouldn't do anything to worsen the situation, but wasn't going to apologize. Even if he hadn't been too proud for groveling, acting like he'd done something wrong would only lead them to agree.
