Zoe didn't think much about Simon, most of her mind was taken up with Wash or whatever insanity the Captain was dragging them all into. But when she did she thought of his first day on Serenity. When Simon had asked if she'd kill him if ordered Zoe had meant it when she said she would. She was always a soldier and Mal was her commander, even if he was a captain now not a sergeant. She might have meant those words but she'd always had a slight feeling, a niggling sensation in the back of her head telling her that Simon Tam would be a lot harder to kill than he looked. So Zoe didn't think much about Simon but when she did she always put a hand on her gun.
