[X] Hint at the truth, see if they bite, ignorance certainly did not protect you (Charisma+Empathy)
There's a reason for this. Yes, they might be safer not knowing. They were safe in canon DF. But Molly needs social peers. People to talk to. You can't keep friends without talking to them. It is selfish, yes.
Some long termish thoughts:
1) For getting money, craft charms would probably be the best. Entirely mundane crafts would be something we could do, and, given how broken they are, we could easily produce a lot of profit. The downside here is that potentially those crafted objects could be used as a conceptual link to us, but that's what shaping defenses are for.
2) On the subject of the crossover cosmology (if this had been discussed, sorry, I am not up to reading through the whole thread right now):
At first glance, the crossover maps easily enough. Nevernever is the Wyld, with different realities being different versions of Creation that at some point were connected by the Well of Udr. Fae are raksha, angels are devas of the Primordial YHWH (or, and more scarily, Theion or some version of him), etc. However, the Outer Gates put a wrench into this mapping. And the fact that at some point both fae courts were human. And the mantles function very close to how exaltations do. So, I would guess that faeries are, in fact, dragonblooded. Or rather a variation of exalted with genetics based exaltation, perhaps directly perversions / mutations of the dragonblooded lines, perhaps something made in their image. Exalted fae in this case would be Outsiders. The alternative possiblity is that they are servants of Neverborn, the dead Primordials still trying to die completely.
3) An imprortant point to bring up: True Resurrection and Time Travel are two things that are canonically impossible in Exalted setting. Full stop. True resurrection is forbidden Doylistically, as a way to ensure "consequences exist" rule. Time travel, however, is forbidden on the Watsonian level, as a direct consequence of the Primordial War, and ensured by the workings of Exalts, the Loom and other mechanisms underpining the reality. This was done, so the beings who invented causality didn't undo their own defeat.
In Dresdenverse, both these things are possible, and, in fact, were observed in the books. Time travel is forbidden, yes, but it can be done. Why is this relevant? Because Yozi are, in a way, the sum of their charms. Because while architects of Creation might be dead, buried, forgotten and painted over, as long as the possibility exists, there's no real way of stopping them from returning. The question is not "will they be back?". It's "who will claw their way out of Oblivion first - Oramus, Ebon Dragon or Luna?"
And this has practical implication: I note the "Brigid's Heir" in out stat sheets, allowing us to learn ancient sorcery once without a mentor or a grimoire. Based on what I mentioned above, I posit that we should learn demon summoning. Why? Because it is my belief that with proper preparation and a lot of luck, we might dredge up something from the Age of Legends. Even if it's dead. And we could bootstrap from there.
