Medbay
As she handed the cup back to the medic for a refill, Sienna almost didn't notice the astonished, even somewhat offended look on Ayumi's face, it was there for such a brief time. Her own forehead knotted in slight puzzlement as she watched her go back to the cabinets and sink. When she heard her comment, the smirk came back. "Yeah, well, I figured maybe you were off on whatever training everyone else is wrapped up in," she explained. She didn't explicitly say she'd actually hoped to find no one in the medbay, given how crummy she'd felt. "I just meant I didn't come here looking for surgery or nothin' over a stupid coffee spill. I ain't a sissy."
She remained seated on the edge of the exam table, patiently waiting for Ayumi to bring her second glass of water, and shivered a little. Before the medic turned around, she momentarily eyed her wadded-up and damp shirt in her hand. Much as she wanted to put it back on, both due to the fact that she was starting to get cold as well as that she was starting to feel rather silly just sitting there in a bra and blue jeans, she knew it wouldn't be too good of an idea. The ointment she'd just applied likely needed some time to breathe in the open air to do its job properly, and because her shirt was still wet and now cool from the spilled beverage, the thin fabric would probably make her feel colder rather than warmer.
Ayumi returned with the cup, and she took it, making a point not to be so crass in her body language or movements. Her headache was already starting to feel better; whatever medication the doctor had given her was working pretty fast. Her throat was still dry and her tongue prickly, however, so she wasted no time in tipping the glass up at her lips and slowly draining its contents. Ayumi's final comment made her grin slightly in surprise as she neared the end of the glass. So the stoic automaton of a ship's doctor did have a sense of humor after all, buried underneath all that professionalism. Finishing off the last swallow of water, she exhaled suddenly, as if relaxing from a midly strenuous activity, as she rested the cup on her lap and regarded Ayumi with a curious, sideways look. "You know, you seem a good bit smarter than the rest of this crew," she observed, pushing some of her unkempt hair out of her eyes.
