It's probably very familiar body language, yes, and Cloud flinches a little just at the sound of knuckles against wood, but looks up after a moment. Opening his mouth, fully intending of at least trying to explain himself, Cloud stops there, awkwardly.

No, he's not, but what to actually say?

He's been sitting here for at least fifteen minutes and he doesn't have any more words than when he slipped in here. Licking his lips, he slowly shakes his head, meeting the familiar blue (it's still odd, when they're not in a mirror, even if there's the difference of the glow as well) before he looks away again.

"... no."
