Oh, I get ya. You're trying to keep her in character. Shy and meek girl who be out of place trying to assert her opinions on others. But Fallen, you would say that Raa is a girl of action, wouldn't you? Not really good at explaining herself or telling others what to do, but certain can do something when the going get's tough. Maybe even act out of her own free will. Certainly would give justification for why Voira would need to be so protective of her; Raa just can't stay out of trouble.

Think of it more as a Tyrael and Mar(or Pylia) relationship. 

Voira doesn't need a reason to be protective. She simply is.
