When it wrecked us: Season four, episode 10 ("Home is Where the Heart Attack Is")
Why it wrecked us: When Uncle Phil has a heart attack and goes to the hospital, everyone rushes to be by his side — except Carlton. Will goes back to the house where he sees his cousin frantically cleaning the kitchen. Carlton admits to feeling scared about seeing his father, who he considers Superman, lying in a hospital bed. Will, who never knew his biological father growing up, reminds Carlton to be thankful for having a dad and encourages him to be there for Unle Phil.
