I take it all back. She was helpful at the end of this quest versus the big boss. Her little spells kept stunning him a little, allowing me the time to press five keys at once thereby inducing more arthritic spasms.
I suppose I'd better show my gratitude by helping her with her own little questy thing now.
And I do hope she says "Gavella glan" one more time. It's not getting on my nerves at all as I just love hearing it echo around my head.
