- Sophie comments that everyone in Halloweentown looks dressed for a party, until Aggie explains that their usual appearances inspired several mortals' Halloween costumes. Perhaps Sophie's comment handwaves any creatures that by post-1998 standards, look obviously like people in masks.
- In the second movie, shouldn't Marnie, Aggie and Luke have more time to work out their subplot, since time goes slower in Halloweentown? But at least in the present scenes the whole world is under the Gray Spell, which could be "normalizing" all magic, including the time difference.
- The word that Kalabar's Revenge uses to activate the Grey Spell, "apart", really does appear nowhere in the dialogue of Halloweentown, not even with a space separating the first letter from the others.
- How exactly did Gwen and her late husband's romance work? They met at a Halloween party...and then had their second date a year later? Or did Gwen get stuck in the mortal world by accident and just decide that she liked it? Did they meet year after year, just elope on a whim, what?
- As a witch with all her powers, Gwen has a lifespan of 1000+ years, yet in the first film she's bound and determined that all of her children are going to be regular humans. This means that she would stay relatively young while her children grew old and died, and she knows it. Maybe Marnie wasn't off the mark with her jab about Gwen getting tired of her kids and disowning them eventually after all.
- But on the other hand, she's presumably aged fairly significantly her +10 years in the mortal world...right? Wouldn't people eventually notice if she didn't?
- Not entirely sure if this is what the previous person was getting at, but maybe being in the mortal world (or possibly, not doing magic) makes her age like a mortal would. Also, maybe the reason she doesn't use magic very often is because she doesn't want to live for centuries more without her husband?
- How old was Gwen when she met her husband? She crashed a Halloween party, but she could have been anywhere from late teens/early twenties to centuries old. Mayfly–December Romance, anyone? And if she actually does have a 1000+ years lifespan, then she knew going into it that her husband would die long before her, too.
- For a supposedly good witch, Aggie has a couple of less than savory spells in that book of hers. (The Grey Spell and the Creature Spell, for example.) Kinda makes you wonder if there was a time when her use of her powers wasn't so benevolent.
- Of course this was confirmed in the fourth movie.
- Confirmed in the first movie: Humans and monsters were at war when Halloweentown was created. Aggie would need spells to defend herself with for good or bad.
- Which could also be explained as knowing the spells with the specific purpose of being able to defend against them if used.
