Ironic title, I know. I tried doing this my standard way, by just healing the NPC, but she runs out of arrows! Just before this quest went gray, I tried it again, this time grabbing aggro and running around a lot until I got far enough to get out of combat. I thought the mobs might despawn if I did that, but I don't think any did. However, I guess it must reset her arrow count or something, because she didn't run out this time.
