(They’re all working on Halloween costumes that are as scary as possible)
Arthur: So what’s your costume, Brain?
Brain: I’m going as the 14th century! This is the castle, and these are the serfs, and here’s a village where false beliefs are taking hold!
Brain: The 14th century!! Don’t you get it?? No hygiene, no movable type, no SCIENCE??
(Brain is so proud of how scary his costume idea is lmfao but his friends are not impressed at all)
