I think that ultimately, both Regina and the EQ, and Jekyll and Hyde, are going to end up merged back together, for reasons stated above. Someone above drew a parallel to the Star Trek episode "The Enemy Within", and I think that this could eventually play out in a similar fashion.

Now, given that William Shatner is a fan of Once, it would be humerously ironic if he were to have a guest role in the episode that resolves the splits (assuming it does resolve with both sides being merged back together).
