Thea explained to Thorne, "Dad, no matter how many questions you give, Theodore can probably handle them. You don't need to bother teaching him math. He really doesn't need it."
Upon hearing Thea's words, William suddenly realized: Thorne was indeed a genius.
He was a genius even more talented than him.
