Of course he picks up on the rising tension. It feels like a bow pulled all the way back, ready for release. That fight or flight response sits low in his belly, but he doesn't move, just continues to worry a thread that's been picked loose. His eye doesn't leave Coil, though, not wanting to miss it when he does start signing again.

He knows it's a lot to take in- it was a lot to say- and even now, Carl kind of replays it in his head. That was... really how he felt. Logically, he knows there's not a problem with it, but there's that small edge of panic. There's nobody around that would second-guess it or tell him he didn't understand. That's kind of the point, right? He did understand. Maybe.. it had been easier to see from the outside looking in?

Either way, he starts to fidget with anticipation. Carl raises his hand in an 'o' before splitting his fingers apart with his thumb in the middle before bringing it down on his extended palm.

'It's okay. Whatever Coil wanted that to mean. If he didn't want to acknowledge it again, that was fine, too. He just worried that something like this would wreck their friendship. All things considered, it's a silly thing to worry about-- something that he may have had to go through if he'd had any sort of normal upbringing, but.. things were different. If he didn't have his best friend, what was the point, right?
