One thing to remember is that both Hyde and Jekyll have reason to hate Rumple. Jekyll hates Rumple because he helped finish the original serum that allowed Hyde to appear in the first place, which ultimately led to Mary falling in love with Hyde (Jekyll's dark side) rather than Jekyll (which could have happened if Jekyll had embraced his Darkness and learned to control it rather than suppressing it). Hyde is ticked at Rumple after being discarded when the experiment failed (from Rumple's perspective). They both wanted revenge.

And there seems to be something about the LoUS where stories are on hold, meaning that even getting revenge can not happen there. Hyde wanted to finish his story (and Jekyll's story) by killing Rumple's love, exacting revenge for the wrong done to them. And Hyde probably presumed that Rumple being the Dark One meant that he had control of All of Storybrooke, and so wresting control of Storybrooke by bringing other people from the LoUS would be another blow against Rumple (this last is my headcanon, nothing supports that viewpoint of Hyde).

One thought that I had from the episode (and really from the entirety of the Jekyll/Hyde story going back to the S5 finale) is that since the EQ is to Regina what Hyde was to Jekyll, could that taser-like weapon be used to incapacitate the EQ and capture her? And will the writers actually think of this?
