Sai seemed to be a little... serious. Was it because of the introduction? Usopp hadn't been totally serious, and he thought he'd probably said worse things about the ninja in friendly terms before, but maybe Sai was thinking about Mello. Usopp still disapproved of the idea of Sai 'training' him, but nodded. "Okay, have a nice night, wish me luck!"

Then, his attention was fully back on Junior. He sat down in response to Junior's sitting, just because it felt rude to stand over the already shorter person and loom waiting. "... Oh, thanks! I need to talk to some people, but I think for now, just having these will be enough. More saltpeter would be good, I wish I had directions for where it is, though. I need to ask Zelnick specifically... or I'll go myself some night." After all, Zelnick had been the first one to show up with it. "Thanks for bringing me these, and good luck tonight too." He stood up, holding the bottles.
