Sans gladly accepts the silence. It's probably a good thing. Gives them both the time to think. For him, he doesn't think about much. He's happy to just let his own relief sink in, despite quietly wondering if Mettaton would forgive him. He'd get it if he didn't. Hilariously, getting an apology back ends up being the last thing on the skeleton's mind.

Then it happens anyway.

"..."

Sans had just plucked the last bit of crumb he could find out of all that synthetic hair. His hand stops. It hovers in the air for a moment. He's quiet for just a long.

"... Hey."

He sets his other hand on Mettaton's shoulder and nods. A hug would probably be better, but Sans isn't sure of the other monster's boundaries right now - that and he has no arms.

"Don't worry about it."

He means it.
