I really enjoyed this. I expected Conveniently Homosexual Engineer, but what you gave us was both more canonically sensical and more interesting. I loved how oblivious Engineer was to the effect he was having on Spy, and how intensely focused he was on the machines. And of course, the banter--there's little I enjoy more than hearing my favourite mercs say biting, horrid things to each other. Carry on, carry on.
