[Teddy looks at him again, lips slightly pursed as he studies his boyfriend's posture and tone. An apology can just be something to placate the situation, after all, and not entirely be true. It's not that he doesn't trust Billy to be honest with things like this; it's just a habit that's lasted for years.

And though Teddy can clearly see Billy's truthful and really does feel like crap, he still isn't quite sure what to say for a moment. He can't say it's okay, because Teddy feels like crap too, so it's not okay, and he's not fine either. Maybe in the past he'd brush it under the carpet, say he's fine and get on with it, but...

Well, he's been evolving along with their relationship.

Finally, he lowers his own head, his own posture relaxing.]

I'm sorry, too. I really should've left something, especially after yesterday. You always do it for me, I just... didn't think about it.
