I agree, Midnight Dreary, that Regina is unusually obsessed with apples. There is an interview of co-EPs, Kitsis and Horowitz, plus Josh Dallas, about what to expect in the run-up to the season finale: There is an upcoming episode that supports this idea of Mills being linked to milo (“apple”):
But the penultimate episode is a different story. I’ll let you theorize exactly what the title “Apple Red as Blood,” means, but I can tell you that it’s part of a final arc that will focus heavily on the major players rather than standalone stories — like the heart-warming one we saw this week with Grumpy. “Next week is who the big bad wolf is. And then we just take off,” said Kitsis. “You’re gonna find out why the evil queen hates Snow White, what happened to Rumple’s son. You’re gonna find out who the stranger is. You’re gonna find out what happened to Kathryn and her disappearance, and it’s just gonna go crazy now.” Crazy, indeed — especially with Mary Margaret and David, Josh Dallas said.
Mr. Gold will act as Mary Margaret’s lawyer after she becomes implicated in Kathryn’s disappearance (and, possibly, murder, Kitsis teased!), and, says Dallas, “Lots of things go down. [David] feels very responsible,” he says. And it will all lead up to the epic season-ender. “All I can say is I just got the script for episode 21 and it is going to go someplace that the audience will not expect it ever to go,” he said.
