It's a dangerous game Cherrycoke's playing here. Often he thinks the sheer volume of information pouring in through his fingers will saturate, burn him out...she seems determined to overwhelm him with her history and its pain, and the edge of it, always fresh from the stone, cutting at his hopes, at all their hopes. He does respect her: he knows that very little of this is female theatricals, really. She has turned her face, more than once, to the Outer Radiance and simply seen nothing there. And so each time has taken a little more of the Zero into herself. It comes down to courage, at worst an amount of self-deluding that's vanishingly small: he has to admire it, even if he can't accept her glassy wastes, her appeals to a day not of wrath but of final indifference...
