I think that the serum counterparts are more like their projection of their Id (versus, Superego/Ego).

So, EQ and Regina are the same people. EQ is just the unbridled passion and impulsiveness. Regina's essentially all the restraints.

It's how Jekyll and Hyde were. When they were together, Hyde was Jekyll without restriants, but Jekyll didn't separate his Id, just sort of turned a switch.

EQ will pretty much not kill Henry, but she's just Regina in all the bad ways (similar to later EQ and Regina in season 1).
