Donnie doesn't say anything. He doesn't feel like trying to explain, and a part of him would like to say that Red Hood is right. If things were normal, Leo would have noticed even before Donnie had gone off. Maybe he had been noticing, but then things have been complicated since he'd come back, and that's what Donnie doesn't know how to explain. It's part of what's been driving him crazy.

Realistically he hopes Leo notices. If this were home, someone would be bound to, Red Hood's not wrong there. It's hard for anything to get past any of his siblings. Donnie wants Leo to notice, the way he'd noticed when Donnie had been away from the apartment, burying himself in projects to try and keep from thinking about the things he didn't want to think about. Things would be normal then.

"...can we go yet?" It's a while before Donnie finally quietly speaks up again, feeling like he's asking for permission.
