At age 24, after various travels, dressed similar to Marlon Brando in The Wild One, Wally returned to his hometown of Twin Peaks to pay his respects, to his godfather, Sheriff Harry Truman because of his illness. He also gave his parents his blessing to turn his childhood room into a study. When his mother asked him about his travels, Wally made a speech, speaking in a Marlon Brando impression.
- Andy says that Wally was born on the same day as Marlon Brando. Brando was born on April 3, which would give Wally the birthdate of April 3, 1990, which would mean that Lucy's pregnancy lasted for over a year.
