From what I understand about this tale is that Mr. Hyde is a part of Dr. Jekyll. If Hyde is "evil" then that darkness was originally in Jekyll, right? So I wouldn't be surprised at all if this timid doctor who just wants to be his good self turns out to be an evil mastermind. Or maybe he /was/ really bad like Regina and did something (to Rumple??) and became so remorseful that he felt the need to do some separating. Since Hyde and the Evil Queen are both the "evil copies," I'm sure they'll team up when she makes her way to Storybrooke.

I can't find anything Sam said about OUAT other than that he was offered the Hyde role and was given a lot of freedom to present the character however he wanted. I like the voice, haha.
