Truth in Fiction

I've gotten hooked on Dollhouse. As I sit here in the airport waiting for my very delayed fight (2 hours, thankyouverymuch) I'm watching the latest episodes. Truth sometimes rings through the words of fiction, and tonight's episode (season 2, episode 8, for the curious) brings us this nugget:

One man is accusing another of being in love with a girl (who, it turns out, he very much is). In a moment of anger (and humor) he accuses: "For months you shared the same room with her, and you didn't sleep with her, even though you could have. If that's not love... are you gay?" Came the reply, "Heh, no."
