The scent of (artificially synthesized) coffee is in the room, and electronics, and at some point someone was eating something like a curry near where she's sitting. There's a smell like warm plastic that comes from the display projectors. Ratthi is not Sitting Still, his leg doing a nervous jiggle-jiggle-jiggle that makes his foot tap on the floor repeatedly. Pin-Lee's nails tap on her mug from time to time. The lack of group conversation isn't a tense thing, everyone is just...working.

And then the door opens with a hiss, the airflow changing slightly as someone in heavy boots (like Security's) walks in with a slow, even gait (that does not sound like Security's). Ratthi turns, and there's a soft sound of surprise before he speaks. "Who is this?"

Everyone in the room turns toward the newcomer at once with their own quiet gasps or curious hums (you know, the sound a person makes when they're just going "?"). And the newcomer speaks, and it's Security's voice, but flat, flatter than she's ever heard it before. "I'm your SecUnit."

And the room goes awkward-still, all at once.
