Right, yeah, their conversation after the gala. Considering Radar was nursing a migraine and three-quarters asleep on his feet, it's a miracle he remembers any of it at all.

"Yeah." He smiles, a little tentative. "I know my hearing's not hearing, always, but some of it is, you know? So when you were talking about how good yours was I just... wondered. Is all."

Hilda squirms in his arms and tries to lick his ear. Radar squirms, too, snickering, but allows it.
