So here’s my real crack theory.
Zelena has already taken Neal’s heart. She goes to her celler, holds Neal’s heart in her hand and tortures Rumple by squeezing his son’s heart as he is powerless to stop her.
This is what puts Rumple back into his right mind as he later breaks out of his cell in a desperate quest to save Neal.
In the scene with Emma and Neal in the forest, Emma has just found Neal. They embrace and kiss. Zelena has already taken Neal’s heart, and he can feel the pressure as if it’s being squeezed. However, just as Emma kisses him, he begins to slowly regain his memories’ of the lost year, just as Graham began to remember. He remembers Zelena. And he remembers her curse.
But then he remembers something else. Something that helped him in the Enchanted Forest. Something very important that he once saw in his fathers shop. Something which holds powerful magic and knowledge.
~~Lumiere~~
…..and…that’s all I have. I just really want Lumiere in Storybrook as well as EF. So, I put him in Gold’s shop for Belle.
