Ōishi is caught off-guard by Jordan's bow and well-accented Japanese. He somewhat hastily bows back to her. "Nice to meet you! I'm Ōishi Shuichirō." He rubs the back of his neck, hesitating. He's not sure how to ask politely how the two of them met.

Eiji's not helping. He's not going to volunteer that information.

Ōishi also notices her arm, but he's waaaaaaay too polite to even think of asking about that.
