Location of Cora’s Heart

The question of where Cora’s heart is is an interesting one, I wonder if her heart is what Rumple’s dagger is to him…I don’t think its in Regina’s body though…I think it would be somewhere in Wonderland…or wait crackpot theory, what if wherever she had hidden it Alice found it and when and if she realized what it was she took it to either our world to hide it or to oz. if she took it to oz I am wondering if she was dorothy over there because she lied about her name..that would be interesting..and it would give Cora a better reason for wanting to go back, especially if it happened right before the curse hit….crazy theory I know but it would be fun…
