Peter Gray, played by Marcus Giamatti: Amy's older brother. He inherited the family business from his father and he's good at it, even if it wasn't his first choice in life. He's a good but grey man who sometimes surprises people with some outbursts. He's married to Gillian and they have been trying to have children for a long time. They agree to adopt the son of a pregnant girl called Evie, and he turns out to be half African-American. Some time after adopting Ned, Gillian gets pregnant and gives birth to Walt. Things get rocky after Walt's birth and they separate for a while, even dating other people. Peter goes through a "rebellion" phase, trying to recall his teenage dreams, until he finds out his business is almost bankrupt. Soon after, he finally reconciles with his wife.
