[Billy's quiet for a moment after that, silently winding another bandage around Loki's second foot. There's something wrong with... a lot of that. Not Loki himself, necessarily, but the words. He's not comfortable with it at all. People are so different- what they want, what they need, what they thrive on or starve without.

It isn't that there's anything wrong with you. Or rather, if there is, it isn't that. Open relationships exist on Earth, and some people are fine with it. Threesomes, too- arrangements between couples to hook up all together- it's okay to want more if you're not satisfied. But that sort of relationship means you need to be completely open- before you do anything beyond your partner. They need to be okay with it for it to work. That's why it's... cheating. You cheat your partner out of what they thought the relationship meant to you.
