I think that it is very possible that Rumpel knows about Red. We know that Red told Snow about Rumpel so she knew something of him. It is also possible that Granny did a deal with Rumpel for the red cloak which stops Red from turning into a wolf.
I was thinking about who could have enchanted Red’s cloak and thought, well, the Evil Queen definitely is not going to care so maybe Rumple was the magician who enchanted the cloak. So, I’m thinking before that happened, Red changing into the wolf — the time that she would spend as the wolf — maybe instead of a few hours — it could have been longer, like weeks or months.
Ruby has those red streaks in her hair. I’m guessing that if she can turn into a wolf in Storybrooke those red streaks are the equivalent of her red hood in FTL. And the girl is always wearing red. She still has her wolf senses. By the way, I still think Dr. Whale is a wolf. I think he might be the wolf from the 3 Little Pigs. It actually makes more sense to me now that we know that Ruby is a wolf. If Dr. Whale is also a wolf it makes sense that he has been drooling all over Ruby – he is attracted to her since she is a female wolf!
