Even the Savior has dark wishes

Except for the way Zelena dies, it could be considered a missing piece between episode 3x30 and the season finale. As Zelena is led to jail, Emma remembers everything Zelena did that hurt her (Walsh, killing Neal, the curse on Hook's lips to steal her magic...) Killian listens to her wish. He decides to grant it for her. Killian/ Gold bonding. Smee helps his captain.
