She seems to be the only one that's capable of eating these aliens. What's even weirder is the stench they release, this might be a mechanism that triggers when they die to scare off predators and to give a warning to others. Ofc they are extremely advanced and probably don't die easily now so they more the often forget. Then here's the problem....how does the smell go away? Simple....they eat their corpses. Sometimes this sort of scent mechanism can backfire and actually tell predators where they are at so they have to have some way in stopping it. The issue is they also taste disgusting so they end up developing a taste for their own flesh. Ofc they over time probably forgot this. Now why does the main character have this taste? Well she was frequently beaten to the point of bleeding, there could have been an exposure point, some of their DNA could be highly contagious(?) and possibly could alter other DNA and considering her teeth aren't normal there might be other parts of her that's been changed one of which is her metabolism and sense of taste.
