I agree on most parts. I say that Regina is the anchor because it would appear that the original serum "brings out the inner beast" and the second ejects that inner beast out from the body giving it form. So, Regina took the serum and it ejected Serum Queen out. Her body is simply magic, so nothing can be done to it. Same with Jekyll and Hyde. It could be noted that the twin blast from Emma and Regina had similar results on Chernabog (a creature of pure magic) as well.

So, the original is the anchor for both personalities. The "Superego" still lies within the body and the "Id" can't exist without the body as they share the same lifeforce. This way, if you kill the body, you kill both, but if you kill the "Id", it simply returns because it's pure magic. It's similar to how Zelena has the pendant that anchored her magic and life force. The pendant had the life force, so when the body was destroyed, it simply regenerated (eventually).

Hrunting hurting Queenie seems weird because the sword doesn;t seem to have any interesting properties. I mean it is enchanted by light magic, but Emma's magic did nothing to Hyde.
