I’m not sure they’d be able to pinpoint it all that accurately but they should be able to notice the difference between such a person’s aura compared to someone with a “regular” one 🤔 as for confirming any theories/suspicions they might have I think subtle digging whether directly or otherwise is in order if the person in question seems to pose a threat……..if not then they’ll just count themselves lucky to have been able to meet someone capable of maintaining some measure of closeness with the divine !!
