HEHEHE. She's aware of other worlds but not multiple versions of the same one. Like the Enchanted Forest and Agrabah and England and all that, since she knows Jafar, Cinderella, Maleficent, Robin Hood & his Merry Men, etc. and isn't originally from Wonderland originally herself. They'll probably have a lot to talk about either way...

Nope, two separate entities in Once Upon a Time-verse (I know a lot of different versions have them as the same, separate, or just one or the other and it gets confusing). She did learn magic from the Queen of Hearts though, so she'll know who that is.
