The Potter heir was just as eager to learn as the Granger girl. Lucius found it surprising that the teen slipped into a Slytherin mindset so easily, and was shocked to learn that Potter was actually meant to be in the Snakes house. (Apparently, the Sorting Hat said he could fit into any house but wanted Potter in Slytherin. Potter argued with it, and ended up in Gryffindor.) Potter easily learned how to utilize the infamous Slytherin mask to hide his true feelings. (Though Lucius got the feeling that it wasn’t so much learning how to, but rather dusting off the ability. It made the blond wonder...)
