Gravelings cannot be seen by humans, but two of them are sitting at a table in Der Waffle Haus moving Halloween candy around on a table. This would mean that everyone in the restaurant would see candy moving around on it's own.
If on Halloween, everyone can see reapers in their true form, why when all of the group were in Der Waffle House, didn't Kiffany say, "Who are you people?" since they would have looked nothing like the group as she knows them. Also when George was with Mason in Happy Times, why did George need to wear a mask, but Mason didn't in front of Crystal? Crystal had seen Mason before whey they were transcribing all the last thoughts of the deceased previously.
If reapers can only be seen in their true form on Halloween, how could Reggie have seen George as George the morning after?
When Rube visits his daughter's and wife's graves, it lists their birth years as 1922 and 1901, respectively. However, in a previous episode, Rosie's birth certificate states that she was born on 03/19/1925. Her mother's age on her last birthday was 24, so 1901 is the correct year of birth, she must have been born between 01/01/1901 and 03/18/1901.
