I'm just re-thinking Sugar's phrasing of "Bao and Xiao Man in the Pavilion again".
I think I didn't understand it at first because, err, how many times have Bao and Xiao Man chatted in a Pavilion? But "the end" and "again" lead me to believe you mean the sequence at the very, very end? No?
That sequence was in a brothel-turned-restaurant. Chinese pavilions are small, ornate, open structures usually situated in a garden. From memory, the only time Bao and Xiao Man were in a Pavilion together was at the start of the last story arc, when they were eating dumplings (ironically, in Xiao Man's own residence, and the occurrence of the first clue to Xiao Man's true identity).
