Adam signs up to be a "Big Brother" so he can spend the day with Echo and her sister.
After Adam finds out that Echo is taking her "little sister" to the school carnival, Adam signs up to be a "big brother" so they can spend the day together. Unfortunately, Derby made a typo on the questionnaire which said that Adam was 41 instead of 14, so Adam ends up with a "little brother" who is older than him. Echo's "little sister" starts stalking Derby while Adam's "not so little brother" spends a lot of time with Echo.
