*Quint frowns slightly, looking worried* Is there some way to make sure they won't teleport away until things are explained? And maybe we should be ready in case either of them need restrained.

*He doesn't say that he's more concerned about that being nessasary for Metal than for Flash, remembering what Air told him about Shadow - that there might not be anything sane left.*

We can't let them go back. It's not safe for them. And not safe for us either.

*He realises something, and almost smiles* Flash probably can't teleport back to the Castle. If it's been years, it wouldn't be in the same place he'd remember it, right? So that's one less thing to worry about.
