Had this been any other situation, Sai might have attempted to take over the bandaging from "Mark's" unknown friend (and do it properly), but he was still a new arrival to the scene and he hadn't been asked.

Tylenol... Sai glanced over at Usopp. Was that the name of the painkiller the pirate had mentioned earlier? It would have to be something rather powerful to ease the pains of the wounds the injured man was currently suffering from. He was also still iffy on trusting anything offered as medication by the staff here.

Without a word, he stepped back a couple steps from the scene to allow the others more room. He knew a crowd when he saw one, at least. A hand laid on Usopp's shoulder would inform the pirate to follow suit.
