Cade looks surprised. Not at Zevran's confession-- it's true, he'd figured that out-- but at the assertion that he's well. He supposes he never saw or felt the transition, but in a way, he can understand where it's coming from.
Or at least, he would if he didn't feel so hideously behind and below everyone else. But that's not something one solves overnight.
"Well I--..." he begins, and halts as usual, clearly unsure of how to proceed. His face reddens despite how well he composes himself otherwise, and he takes on a vaguely frustrated expression, the sort that appears only when he's fully aware of how impossibly awkward he's being.
"...I'm not sure it's. Not." He chews the inside of his cheek, resisting the urge to bolt. "I don't know. Never mind."
