There were spoilers pics from 2×18 of Charming, Snow, Emma, Baelfire, Tamara, Henry, BF, Pinocchio/August, and Geppetto, so they’re safe for now. We can also rule out Rumple and Belle, who are both in spoiler pics from episode 2×19. I think Regina and Hook are safe, since both were confirmed at Paley Fest to make future appearances.
Yet, I haven’t seen Ruby, Granny, the dwarves, or Jiminy around lately. 😕
