2B takes in the explanation. 9S is interested in it, and that's enough for her to be as well, though hers is a less intense wonder as little bits of water splash and fall on it. "It's cool." She comments idly, and wonders if maybe that is why humans might have kept themselves dry.

But 9S is reaching for her visor now, and she can see his nervous expression, the way he hesitates.

2B is fully capable of removing the visor herself, but she nods all the same, slow and sure. "Yes."

She has no right to deny him anything.
