When I first watched, I was hoping that Wishverse Robin would be a way to have his character back permanently, a second (third?) chance for Outlaw Queen's happiness brought about by Charming's wish that the Evil Queen get what she deserves. I guess I didn't pay enough attention to the "Evil Queen" bit or thought of them as 2 halves of one character.

Anyway, I'm happy that they got engaged - and I love the arrow shot proposal, perfect - but I'd still have preferred any version of Robin with Regina herself.
