[He stops, seething. Normally he'd listen, and normally he'd probably have sympathy, maybe help Epsilon think of a way around it. The problem was, that was normally, emotional blank slate territory, and right then Wash was beyond sympathy and empathy and beyond pissed. He doesn't look at Epsilon while he's talking, voice a bit calmer on the surface than it had been before. That doesn't hide the bite, the danger in his tone.]

Doc once told me I couldn't kill everyone I met. When I asked him why not, he couldn't give me a straight answer. I'm still waiting for one.

And I thought I told you to leave me alone.

[That was the verbal equivalent of a warning shot. Stop him from leaving again and things will likely get nasty. As it is, Epsilon is pretty damn lucky that Delta and Theta like him and that Wash cares about those two.]
