He watched his captain hold the girl firmly in his arms, and he knew this would present a problem. He didn't realize that the greater problem lie in the fact that he hadn't been able to continue his work when he pulled her there.
He watched him pull away and kiss her softly, through the window, down on the street. Though he didn't understand it, he couldn't shake the unsettled feeling form himself.
He moved back from the window, shaking the sight from his mind. No, he couldn't worry about that now. He had a computer to build.
So he let his mind skip about equations and he let his fingers jump nimbly across his materials. He quibbled with his brain over any other subjects, but with an apt ability to multitask, he lingered on the kiss the two outside the window had shared, and lingered on the feelings it brought to him.
When his captain returned to him that night, he said nothing of what he had witnessed, he said nothing of feelings he did not understand, he, in fact, said nothing at all. Instead, he choose to hold the natural mask to his face and work in silence.
