[ what...is so hot about mapping the mirrors? At least Holtzmann agrees, in her own Holtzmann sort of way. Everything she likes is hot, probably.

Erin nods, a little bewildered at the aviators. ] Yeah. They're, uh, not exactly safety goggles? Not that you should need those for mapping, anyway.

[ Erin does put two and two together. She doesn't want the beings on the other side to know what they're doing, true. ]

Blindingly reflective as in basically, effectively, invisibility? [ Huh. It's been theorized before, enough times to probably put it into practice. Erin would know. ]

Okay, but they can't interfere with the mirrors, otherwise the whole expedition is pointless.

[ Erin takes the Ray Bans, gives them a long, hard stare, and finally slips them on. ]

I look like an idiot, don't I? [ she says, deadpan. ]
