Raiden saying "I can protect you, D'Vorah" suggests she may have a certain doubt about her allegiance in some part of the story. Also, Kotal saying "With which face do you see me?" may suggest a double personality from one of them, or maybe one of them was a character who appeared in MK9 under a new alias.

Okay, now considering both, think about this: D'Vorah is someone that already appeared in MK9 (or another character we already know) and sided with Kotal Kahn (maybe out of rage), but then, something makes her have doubts about the allegiance and Raiden wants her to return, but she still refuses. Or maybe she just feels betrayed by Kotal Kahn at some point...
