Shouldn't there be a way to determine if someone looks or keeps looking at you while in character? Something like 'you feel X looking at you from the distance' or 'you notice X watching you' when someone looks at you? This all being dependable on PCP rolls and the location. Flashing lights, being in the dark and the likes affecting these rolls, naturally. Ain't sure if this is already been a topic before, didn't find anything with a quick glance.
