more thoughts,
zach really hammered in that marcus was gay it seemed. shopping for fruity pebbles in the store, his husband and himself about to share 6 hotdogs, the campyness that his husband showed when gladys burst into their home. kinda on the nose with that
kinda weird that gladys whether intentionally or unintentionally looks like a clown, and her last moments were pretty damn comedic with her running from the kids in the neighborhood... i mean until her gruesome demise.
gladys has to be old as shyt based on that cosumption line, so her pied piper ass has probably been making kids disappear for a long ass time. modern technology must have been kicking her ass with cameras and info being passed around in the blink of an eye. so she was probably on borrowed time one way or another.
ive seen a few people assume that alex being able to use the blood magic means that the magic is in the tree, but it makes me think that alex is the reasoning behind gladys being in town all together. through observation he replicated that spell with ease, and it makes me think her true goal was to take the kid and use him to continue helping her
As far as the boy
when those kids entered the house didn't he have on a superman shirt? If so then I'd say you are correct

will be pleased to see more of Auntie Gladys
