Cameron’s older, single sister Pam (guest star Dana Powell) is coming for a visit, and Cam is in a panic to hide the engagement until he can delicately break the news to her, but it turns out she has news of her own. Phil and Claire make a joint, guilt-ridden decision to miss one of Luke’s soccer games – that is – until one of them goes behind the other’s back, and Gloria is in denial that she might need reading glasses, on the 100th episode of “Modern Family”
Shawn and Gus show up at a crime scene at a swanky mansion where a young bachelor, Lance, just fell to his death. Lassie doesn't believe it was murder, but Shawn thinks otherwise. He notices that Lance's ankles and arms were not broken, causing him to believe that he didn't try to brace his fall and was therefore dead before his body touched ground.
