I’m so emotional about astronomer!cas though. Spending all of his time under the night sky looking through telescopes. Always getting teased about having his neck craned back and staring up with bright eyes. He’s basically nocturnal with all the nights he stays up until dawn, observing the Milky Way and supernovas and comets blazing across the sky. He talks nonstop to dean, a sweet mechanical engineer that maintains the observatory equipment, about the ludicrous notions of astrology and horoscopes and “what the hell is a Capricorn anyways.” They kiss for the first time when cas excitedly drags him out the front door to see the meteor shower raining down streaks of light. He smiles the entire time.
