[Skulduggery adds to Kratos's answer.] There are two of them back at my house, guarding a teleportation pad. That's all. We won't need to worry about a few hundred thousand angels descending at once. As for other risks, we can't be the only ones who've noticed something is strange. If Kratos's descent didn't raise an alarm anywhere, there are always strong Sensitives having prophetic dreams they choose not to ignore.

[Valkyrie seems to shift out of a trance.] -- wait, did you say a teleportation pad?

And as Kratos's descent was powerful enough to crack the street, I think we can assume someone somewhere noticed it.
