Wow, she's REALLY avoiding giving a direct answer to Huilii. How long are you going to keep this up? Because honestly, if someone was avoiding giving me a direct answer to a quest I asked something that was really important to me, I'd be yelling at them.
Hmm - mitigating factors might be, she (and most Draenai youngers) are brought up to respect their elders, Huilii does have some affection for her (essentially) caretaker, and this is all supposed to be secret- too big a protest might alert everyone else, especially the undesirable warrior/priest/general-dude who is after her skin. (And yes, that can be read in several ways :p )
