Let's say if someone, hypothetically...may or may not have watched somebody run into a burning building, went to follow them and then the building exploded. That kind of thing. And then that same person ended up getting separated from the same person who was killed in that burning building and found out they'd been killed again because of a different fire and came across their corpse in the middle of nowhere.
