6. Jack tells Randall it's OK to be different
"Career Days," Season 1, Episode 6
Randall isn't like the other Pearson kids. He's adopted, black, and, it turns out, a genius. As if the first two things aren't hard enough, his intelligence only further others him as a child, when report card As are rewarded with ice cream cones and parental affection. Randall doesn't want to be treated any differently than he already is, and so he lies to his dad about his mathematical abilities. But Jack knows, and puts his son to the test, under the guise of helping him with work. When Randall resists, Jack asks why, and his son lets it be known how ostracized he feels. Jack processes this, before telling Randall that it's OK to be different, and that he is as much his son as his other children are. "I love you as much as a human heart can, kiddo," Jack goes on, cementing his status as the world's best dad. "You are an exceptional young man." Future Randall becomes a millionaire weather trader; we see the seeds of that success planted by his father's words.
