It was a little argument that turned into something... a lot bigger. Clark wasn't angry, no. At least, he kept telling himself that he wasn't.

That, of course, was called out during said argument. That Clark gets upset then tries to play it off like he isn't actually upset. And then he deflects, and then he leaves...

Okay. Maybe Clark does have a few slight issues.

He allows himself back into the apartment in silence. By now, it'd be way past the usual time he went to bed with his other half.

"...You're awake." Clark whispers. His tattered cape flutters behind him. Tenderly, Clark shuts the balcony behind himself.

He can't find the words to say. Not yet. But what Clark can start with? "I'm sorry."
