"You and him both," Nigella chirps, as she looks up at Cole. Cole, in response, blushes slightly. Rita knows about him having an identity crisis and thinking he wasn't real (and then learning he was). What she's going through is kind of like that but obviously different. After all, Rita won't change like he did.

"It's...odd, learning you're something you're not. But it becomes you in the end."

The whole 'realizing you're a spirit and then becoming a spirit' thing was intensely odd and slightly difficult, but Cole likes to think he pieced it out eventually.
