Cade tenses further when Beleth angles her head. He's beginning to look like a realistically-colored statue with a vaguely terrified expression. He has no basis for either relating to this or assuaging it, because despite perhaps having the occasional favorable feelings toward someone, it never even occurs to him that they might be reciprocated. He quits while he's ahead, invariably. But that's not what Beleth wants to hear.
"Sorry," he murmurs again, this time apologizing for not saying what he's supposed to.
But upon Beleth's decision, he shakes his head quickly. "Wait, don't," he says, "you should, um. You should go to bed." He's dealt with drunken brothers in arms before, he knows how this works.
