Once Upon a Time: This Fan Theory Might Mean the Death of Your Favorite Character

Notice that in the 100th episode, when the heroes go to the Underworld, David is wearing a black jacket with a plain collar.

But when his brother James briefly poses as him, he's wearing a leather jacket with a metal buckle on his collar.

Now take a look at these recent set pictures from the season finale. Notice the collar? With Rebecca Mader (aka Zelena) present, it appears the gang has finally made it out of the Underworld. But if that's James, where is David? In more set pictures from the same day, Snow and David hold hands in a scene. Because Snow would never knowingly hold hands with James, she might be under the impression that he's David.

This potential plot line is devastating, and don't forget that the writers have already confirmed that there will be a "death arc" this season. While they didn't elaborate on what form it would take, this could be a loophole: David loses his soul to James, "dying" in a sense. Remember that Snow shares a heart with David. If he is left in the Underworld, what becomes of their shared heart?
