actions, which causes him to realize the error of his ways, and he officially ends his relationship with Donna, via a text message. In "Sex Ed", after Michael discovers that he may have herpes (but it is simply an ingrown hair, not genital herpes), he contacts all of his past lovers, starting with Donna. He calls her, and while she is initially pleased to hear from him, she is mortified when he reveals his STD to her, as she fears that he may have transmitted it to her. Lucas "Luke" Cooper (Evan Peters) is the son of Michael's half-sister, from whom he had been estranged from 1995 to 2010, as a result of losing Luke in a forest as a child. In order to make amends for the incident, Michael hired him as the new office assistant sometime between the episodes "Whistleblower" and "Nepotism", although he quickly proved himself inept at his new occupation. Luke is particularly disrespectful during a meeting, so Michael loses his temper and roughly spanks Luke, who is humiliated and tearfully leaves the office. Jim's family/loved ones Gerald (Robert Pine) and Betsy Halpert (Perry Smith) are Jim's parents. In "Frame Toby", Jim purchases their house, where he grew up, for him and Pam to live in.

During lunch, they make numerous insults towards her art career, causing Jim to come to her defense. After the argument escalates, Tom and Pete reveal it to be a prank, with Pam awkwardly confirming this. Afterward, Jim receives a text message from them welcoming Pam into the family, and Pam suggests they should "prank" Tom about being bald over Thanksgiving. They later reappear in "Niagara", attending Jim and Pam's wedding, for which they (along with Michael and Dwight) organize
