Lucifer Morningstar: A celestial impregnating a human... How is it even possible?

Amenadiel: And, if it is, how has this not already happened to you?

Lucifer Morningstar: True. Mm. Maybe there's another explanation.

Amenadiel: You think Linda's an angel in disguise, don't you? I've been wondering the same thing. Maybe she's not even human.

Lucifer Morningstar: Or, maybe, when you lost your wings, you became as mortal as it gets. Maybe you became more human than you realized.

Amenadiel: Oh. Probably makes more sense.
