[In other words, it's a complicated situation. Unrequited love? Situational affection? Messy, messy. And not for the first time Billy finds himself feeling grateful that he'd started dating Teddy before their lives were any more dangerous than "Kang the Conqueror might show up and try to kill us".

You know, besides the usual Teddy is perfect kind of gratefulness, anyway.]

It's okay, really. If I can help somehow, I don't mind. But if you're worried the other person doesn't feel the same, you could just wait it out, see what happens. My experience is that people in love aren't all that subtle.
