Regina Mills, or the Evil Queen?

All the people in the town of Storybrooke, has two personas. The one of the town that had been created by ****, the other of their original selves from the Enchanted Forest. With one exception, only one of them had both personas before the curse broke...

Regina Mills, the Evil Queen, who cased the **** curse.

A perfect person to receive the power of the Stones, as good or evil, she would use them for great things. The question is which version of them would get the stones? Regina, the Evil Queen of the Enchanted Forest? Regina Mills, Mayor of Storybrooke? Both of them at the same time? What story will we see, Once Upon A Time?
