I think reintegration will be simple. I think it will boil down to the fact that Regina needs to accept the EQ side of herself, rather than fighting against her. This plays into the foreshadowing we saw in the conversation between Rumple and Regina in NYC. And by accepting the the darkness and reintegrating it with her, Regina will be able to maintain control over it, winning the war that is raging inside of her (something the Dragon hinted at).

However, reintegration of the EQ was not a part of Strange Case. the only thing that we really know for sure is that in order to kill the EQ, Regina must die. (and I don't see that happening anytime soon).
