Just some random thoughts:

Betty actually likes Nancy Drew? That's a bit of an eyeroll moment, but it totally fits the version of the character that they're going with. Really, the whole bland/vanilla appearance that they put on Betty in this series is a bit too on the nose. I mean...she literally drinks "old-fashioned vanilla" milkshakes.

How can Cheryl be in three scenes but not have any lines? That, like, breaks the rules of awesomeness.

Pay attention in the town hall scene. When Fred's speaking, Hiram and Hermione are literally the only two people not looking at him. Wonder if that means anything.
