Chemistry education really hits different over time. One minute you're learning that sugar is solid, water is liquid, and steam is gas (revolutionary stuff!). Next thing you know, you're staring at cobalamin's molecular structure like it's some kind of eldritch horror summoning ritual. The facial expressions capture that journey perfectly—from "this is fun and easy!" to "what unholy molecular nightmare is this and why does it contain cobalt?!" The jump from states of matter to vitamin B12's structure is basically the chemical equivalent of going from "The Cat in the Hat" to "War and Peace" written in hieroglyphics.
