Right before the end of the sixth season in "Point of View", Mac is injured from chasing a murderer. During his recovery, he sits on a chair in his apartment, which is positioned at his window, allowing him to spy on his neighbors (in a Rear Window-esque way). However, he witnesses a man visiting Mac's neighbor Kevin Scott, who is a former university professor. Hours later, the man is found dead. Later, Mac sees him poisoning his canary until he is interrupted by a visitor, unexpectedly to be Peyton, Mac's ex-girlfriend whom he hasn't seen for over three years since his visit to London with her. He tries to convince her that Kevin is behaving suspiciously and that he killed his canary, but she thinks he is jealous and tells him that Kevin is just her friend. They talk about the past and they rekindle their relationship. Mac tells her that he missed her after she left him for her family, to which she apologises, but he understood that her family is more important. Kevin's actions are proved to be criminal when he plotted to expose a group of people to a highly contagious chemical substance and he is arrested. Before the credits, Mac and Peyton look out of his apartment window amusingly, witnessing a couple kissing when a woman is about to catch them in the act.
