Has anyone else noticed how many incomplete tales there are in Once Upon a Time? These are tales that have only had one or two characters shown, but could be elaborated on. For example:

Mulan: We've only seen Mulan.

Peter Pan: We've only seen Captain Hook and Smee.

Alice in Wonderland: We've only seen the Mad Hatter and the Queen of Hearts.

Aladdin: We've only seen the genie.

Rumpelstiltskin: We've only really seen Rumpel, they haven't come right out ON THE SHOW to say Cora is the Miller's daughter.

King Arthur: Lancelot

Mythology: King Midas

If you can think of any other examples, post them in the comments.
