While Jake was getting the beverages, Kesha attempted to make small talk with Nog, who was in the process of recovering from the loss of a leg.
She told Nog how Jake had told her that Nog was going to be the first Ferengi captain in Starfleet and that Nog was "quite a hero." Nog replied modestly at first to her compliments, before outright scolding her for patronizing him.
After giving up on the conversation she inadvertently glanced at Nog's cane, then his biosynthetic limb. Nog instantly noticed and began giving Kesha a hard time, pointedly asking if she was wondering which leg was his new leg.
Moments later Jake arrived with the martinis, when Kesha suggested that it was time to leave. Confused, Jake wondered what had happened, but eventually figured it out. Kesha apologized for making Nog uncomfortable, but he dismissed them anyway.
