Took me a minute to figure that out, but I'm not a fan of OUAT.

But I do get the crossover. Very cute.

Reminds me of when John DeLancie (Q from Star Trek, among other roles), was playing a character on a soap opera - Days of Our Lives - and one day he just disappeared with no explanation. He played a pretty flaky character with a pretty flaky girlfriend and one day someone asked his girlfriend if she'd heard from him and she said "Oh yes, he called the other day. Said he was an all-powerful being in another dimension now."
