Very. Why?<br/><br/>What are you wondering if she'd be able to detect? We've already discussed that so long as his demonic nature is in its current dormant state, she can't smell it. (I explain this to myself in that whatever demonic bits he might have simply aren't pumping out demonic hormones, therefore, no demon smell)<br/><br/>Speaking of, she can smell hormones. As in, chemicals inide the body such as adrenaline and other things released in response to stress or other stimuli. Of course she'd have to be fairly close to get that much info on a person...but she can pick up pheromones (chemicals released externally to carry messages via scent) over several miles if the wind is right.<br/><br/>That and I'd imagine hell hounds are particularly good at tracking things (hince her 'ultimate' ability of being able to track a person over an infinite distance, though that's more a magic ability than one based on the physical ability of her nose or any other sensory organ....more like taking a part of the person into her soul so she can hone in on them spiritually) So....I guess as a general comparison of physical sniffing ability, couple steps up from a bloodhound?<br/><br/>The lore for her people I've built in my head tells me their sense of smell was one of the things that made them so useful to the demons they used to serve.
