Kaylee dropped the wrench when Mal's voice echoed through the cargo bay of Serenity. She hadn't known Mal was around, or awake for that matter. She'd been so busy dealing with the engine and other problems she hadn't been paying much attention to people at all. Kaylee winched when it clattered on the floor and echoed one again.
Great. She really liked that wrench.
"No, I wasn't plannin' to captain! Just answering the knock is all, never know who would be knocking on Serenity like that. Could be someone got locked out or somethin'." Kaylee looked sheepish and reached down to get the wrench.
Hopefully Mal wasn't in a bad mood. She wasn't keen on watching some kind of gun fight or yellin' contest. Kaylee out the wrench back in her pocket and pushed some hair out of her face. "I'm sorry. I suppose I should head back to the engine room?"
