So what is the Knave’s history with WL? He’s the Knave of Hearts so I’m assuming he worked for Cora at some point. Did he guard people’s hearts? Did he take them?
We already know the Knave of Hearts (i.e. Will) is a thief, since he stole Alice’s shoes with the wishes. Also, I believe in the original tale of “The Adventures of Alice in Wonder” and/or its sequel “Through the Looking Glass” the Knave of Hearts had stolen the queen’s tarts, which could easily be changed to him stealing the queen’s hearts.
Also, according to spoilers, the Knave of Hearts is actually one of Robin Hood’s merry men. His real name is Will, which means he is probably Will Scarlett. He might have been stealing from the rich (the queen of WL), then he escaped, and Robin Hood recruited him to steal from the rich to give to the poor .
