Pavlovian Intentions-Freewood

It was impossible to tell by appearance that Gavin was an android. Hell, if you were to have a conversation with him one-on-one, you'd still think he was human, and nothing would lead you to believe otherwise. Only when he was beside his husband was one able to find subtle clues that let them know.
But things go different when Gavin begins to feel things no robot should be able to understand.
