Red Riding Hood is so far the only character who has not met with Rumple. She only mentions him to Snow using the word “whispers”, meaning to me she has heard of him. Granny may have had a dealing with her, when she says to Snow with regards to the cloak, that she got it from a “wizard”. It could mean Rumple or the Wizard from Oz for those who are anticipating an episode about Oz. Ruby in Storybrooke has met him and knows who he is.
