Bird's 'greeting' gets a bit of a nod from Callaghan, but he's more intent with the fact that this place is...well, even more sparse than his is. He's got shelving, some basic furniture, and Akito has...

...almost nothing. It makes the space seem bigger in the worst way, empty. Robert gives Tadashi a look, furrowing his brow, then makes a decision.

"I'm fine, but why don't you let me make some, anyway? Tadashi can help you get settled. We'll keep quiet while you rest."

Why yes, he does feel uncomfortable leaving, now that he knows Akito's place is in this state.
