Long before Nicholas Braun appeared in Succession as Cousin Greg Hirsch, he starred in a TV adaptation of a beloved '90s teen romantic comedy. The black sheep cousin of the Roy family, Greg Hirsch, is one of the funniest characters to come out of Succession. Introduced as a high mascot at one of the Waystar parks, Greg somehow works his way up to the number two position of the CEO of the American subsidiary of GoJo. He has trouble speaking coherently, can't read a room, and rarely gives more than he takes, but it's hard not to love him.
