Steve's usually pretty good at keeping his mind on his work. But after being denied the assignation with his world's Tony, and little chance of seeing him again for a while, there's something pent-up inside him, something Tony's only just started bringing to the surface.
So when Damon talks about 'phallic vegetables' and 'cumming with every bite', Steve is suddenly made acutely aware of his denial. He gets caught up in thoughts of Damon...looking at his muscular arms under the sleeveless shirt, imagining what the rest of him looks like beneath the cargo pants...
Distracted as he is, Steve almost doesn't hear the engineer lamenting the horrible food conditions on Sera, but something inside him remembers camping out with the Howling Commandos in the Alps, huddled around a fire in the snow with only the military rations to sustain themselves.
"Damn...I've been there. It's not fun."
He turns on the stove with a grimace.
"That's one of the main reasons I learned to cook; didn't want to be stuck with the military's excuse for cuisine."
