The third season of Once Upon a Time aired one of the most heartbreaking scenes of the whole series. The mid-season finale saw Peter Pan threatening to cast a dark curse that would torture the heroes for all eternity. The only way to stop Pan was for Rumpelstiltskin to sacrifice himself. So thats what he did. Rumpelstiltskin used the dagger of the Dark One to kill Peter Pan, selflessly sacrificing himself for the safety of his family and loved ones. This scene was so heartbreaking as he had to sacrifice himself in front of his true love and his family.
