"Pleased to meet you." Hakuba lapsed into the more Japanese bow - he'd caught the name, and was used to culture-juggling. "I hope I'm not a bother - I've lived in Paris before, so it's not hard to help when someone's lost." He wasn't about to pull an attitude with an unknown person, particularly not around Aoko, and it'd make it harder to get a better idea what'd just happened to the already chaotic polygon, anyway.
