This causes him to be insecure about his acting ability. When he gets ready to debut his new play in front of an audience, he panics and seeks the encouragement of his family. Looking for his mom, he instead runs into Miguel, whom he dislikes. However, it is what Miguel says that increases Kevin’s abilities:
“You remind me so much of Jack that sometimes when I see you the hair goes up on my arms, because for a moment it is like getting my best friend back. You are Jack Pearson's son. You have him inside of you. And when you're nervous or at your most nerve-wracking moment, the curtain's about to go up, all you have to do is remind yourself of that, and you'll be fine.”
As he struggles with creating meaningful art and making a difference in people’s lives, he has always been jealous of Randall and the attention Randall received from his parents. While the rift is evident for many years, instead of Kevin needing Randall’s help, it is Randall who now needs him as Randall is paralyzed with fear. Kevin, when the curtain goes up, remembers these words and instead of going on stage, helps his brother.
We all have choices to make in life. Will you do the right thing, or think only of yourself? Will you sacrifice my credibility to help a friend in need?
Jack Pierson’s son did the right thing. Be Jack Pierson’s son.
