It is definitely something Regina would do, especially now when she is on the brink of turning into her Evil Queen persona again. She will probably use blackmail in order to make him help her to get rid of Marian. I don't think it is Hook, especially now when they turned him into goody-two-shoes and Emma's love dog so it would seem so out of character. The other possibility is that Elsa is the one who is blackmailing Rumple, she i supposed to be a misunderstood villain so this could add to people misunderstanding her. But problem is - I doubt creators would go this far with her character, they weren't even bold enough to change her dress yet alone her personality. Another candidate that seems likely is Elizabeth Mitchel's character whoever she may be. But with all this said I guess Regina is the most obvious one.
