Robin Hood got Regina's sister pregnant! Yeah, we know he thought it was his once presumed dead wife but we still think he's got some explaining to do.
Now that Emma has brought Lily to Storybrooke to reunite her with Maleficent, can she trust her old friend not to seek revenge against Charming and Snow White?
Either way, it's going to be one heck of a reunion when Emma finds her long lost friend and tells her the identity of her mother. "Lily" is the 20th episode of Once Upon a Time's fourth season.
