Permanent death, I’m calling Mal. The show doesn’t need two Dragons. With Lily on board, Mal is now expendable and Mal’s death would surely set off her daughter.
Temporary death, I’m going with Rumple or Emma or both.
Finding out about AWB knowing about Neal, I’m going with the Apprentice. He’s already presented himself to Lily and did a course correction. Makes sense he did the same with AWB.
