Also, it was of Emma to have like no problem with taking Past Marian back to the future and yet she told Rumple to drink the memory potion to forget about saving Neal. What? Emma didn’t want to alter the past but she brought back Marian? That makes no sense either.
It was completely hypocritical of her.
And no, there’s no way I can believe that Dark One Rumple, who was OBSESSED with finding his son for CENTURIES would just shrug off the fact that he died and not even attempt to change it.
