Actually, we both think you tracking might be a bit better than trying to summon her. Summoning her could work, but if you can track her, pick up her scent, it'll be easier to catch her by surprise. Do you think you have the ability to tail her for a bit without getting caught? Maybe see where she'll be, how many she has around her, that sort of thing?
I'm also not sure how much of her scent would still be on the clothes Kim was wearing when she was attacked. But I'd think there was definitely still a trace. Will it work?
