@Stitches It depends on the hunter. We got tracker types, sailor rogue types, my char's a vampire pretending to be a holy manhunter for a noble family, we got that fur coated ranger poison girl who's big on stealth and agility too, and so on.
That's what I'm thinking too. Abigail's by no means a professional, too, so it might be that she can be spotted by the PCs but not really by the NPCs/enemies unless they're looking for her? That seems far more reasonable. After all, she has got the experience but some of it is raw talent simply because she isn't old enough to be that good just yet. And professional hunters need to be able to know when something's sneaking up on them.
that being said, I'm totally down for Abigail jumpscaring people for shits and giggles if they play along.
