"She did." But didn't seem to know how to use them, so all he can do is wait and hope Will can instruct her even though they clearly despise each other. It's one of those things they'll need to set aside so they can make some progress.

"Flying would be risky," he acknowledges, but nods as he considers it. Yes, everyone else has gone by land. The jellyfish spirits were capable of a sort of flight, slow and gentle, but he hasn't seen anything with actual wings yet.

So maybe it would be doable. Maybe they'll get themselves killed, but maybe they won't. And the payoff, should they succeed, would be immensely beneficial, wouldn't it? To really know what's in that lighthouse that Robin refuses to tell them. If he were to speak purely out of concern and safety he'd tell Aziraphale no outright, but if he's willing to chance it, they could all stand to gain.

"If you do that, be ready to leave on short notice," he cautioned. "If you can't take things, take photos. Find out as much as you can."

If the spirits attack, if somehow Robin is killed, they'll need to be ready to replace her if they're to stand a chance. But if one of their number becomes the new Keeper, they might find themselves with someone far more cooperative in that position wouldn't they? Interesting.
