Maybe the dots had grown to hate the inhabitants of Finetown so much that they just enjoyed watching them get eaten by slugs. I mean sure they could just headbutt them to death...but which is funnier?
After the end of the episode I can totally understand that point of view.
I am also very confused about the slug part because the dot is supposedly killing in alphabetical order. Yet the dot was going to have her walk into a slug in the elevator a while before her name was up.
Apparently this entity cares so much about the alphabet it stopped targeting her to go after the september guy so what gives?
Someone theorized the slugs may hold you and kill you off when its your time but the list the dr uses to realize its in alphabetical time isn't time of death, its time of disappearance. These slugs do capture on video so If people cant have been alive inside a slug without anyone or themselves noticing.
