The Among Us Show is incredibly tight for a show with such a short runtime and so many characters. I think a big component in how they achieve that is the fact that every single detail you learn comes back later--as a plotpoint, a joke, or usually both.
Red bonds with Green by talking about how they were once a lowly intern too who got by on stealing pizza crusts (and Green goes "woah you can do that?") This comes back later both when Purple reveals the shared internship is the origin of all their problems with Red, AND during backpack check when Green tips over their backpack to reveal it's now full of stolen pizza crusts (which Red pretends to be disappointed in.)
Yellow and Brown's game of "we both answer the question with the same thing at the same time" falls out of sync when Yellow answers flakey salt for favorite pizza topping and Brown says none. Flakey salt of course comes back both in the emotional fallout of Yellow's death and in the manner by which Red and Purple defeat the imposter.
Black complains to Blue that MIRA gave them no equipment except a microscope they have no use for. The microscope is what Black later users to confirm the alien residue on the cracked ore.
Lime tries to open MIRA's 'weapons' storage only to discover it's actually the 'weird aprons' storage. Later when Yellow is lecturing Cyan and Purple about being in the freezer, Yellow tacks on "And have you been messing with our weird aprons?"
Orange opens with the trustball fact of having two pairs of shoes: one for normal wear and one for when they're feeling sumptuous. At the very end, Purple is keeping Heracle's body in the 'sumptuous' shoebox.
Lime's "I'm an ordained minister" comes back int he fact that their weapon against the alien is literally just useless holy water--which can be made not-so-useless when paired with flakey salt to make salt water.
