These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Logic: Afterlights cannot age in Everlost, but Nick is described as a fifteen year old in Everwild when he was fourteen when he died.
Nick's probably just one of those people who look older than they are, and other Afterlights mistake him for a year older. Having half his features covered in chocolate probably doesn't help on that front...
Moral Event Horizon: For Mary being Mary, and especially Jackin' Jill, who skinjacks people to kill children, prevents them from reaching the tunnel to the light, and bringing them to Everlost instead.
