Raj and Anu have to decide what accepting the job means for their relationship. And Anu, at a concierge conference in London, telephones with the news that she has been offered a managerial job in London, that job which she is seriously considering. As such, Stuart and Denise try spending a night in at her apartment, even if her 'creepy' roommate Mitch is there. Does Beverly have an ulterior motive in her behavior or has she truly come to see Leonard in a more loving light? Meanwhile, Howard and Bernadette are uncomfortable with how much time Denise has been spending at the house, even when Stuart isn't there. Joyce Kim was mentioned in the pilot, 'The Codpiece Topology,' and 'The White Asparagus Triangulation.' She appears in. The two dated for 27 days, after which Joyce defected back to North Korea, as Howard and Raj recalled in 'The White Asparagus Triangulation.' She has been mentioned several times and seen once. To Leonard's surprise, Beverly, upon her arrival, seems truly interested in and eager to spend time with him, the criticizing 'but' which doesn't seem to materialize. The twelfth and final season of the American television sitcom The Big Bang Theory premiered on CBS on September 24, 2018. Joyce Kim was one of Leonards former girlfriends and a North Korean spy. Raj insults physicist Neil deGrasse Tyson and starts a Twitter war. Penny and Leonard discover they are uncomfortably similar to Amys parents. For Beverly's visit, she has accepted Leonard and Penny's invitation to stay at the apartment with them rather than her usual routine of staying at a hotel, that offer which Leonard may regret in the continuing strain he has with his mother. Sheldon and Amys honeymoon runs aground in New York.
