Draco would show him all his beakers and bottles and set up for his personal chemistry lab. He would talk for hours about different scientific advancements that had been announced in one of the science journals that Narcissa had subscribed him to for his birthday, and Theo would sit in one of the desk chairs and allow the blond boy’s voice to roll over him. He would ask questions when one occurred to him and Draco would be so excited to go into further detail about his interests. Theo laughed when the boy pushed his glasses over his fine aristocratic nose and launched into some very jargon-based explanation of some chemistry or physics discovery.
