Sheldon and Leonard are happy playing a board game until Amy and Penny say they are tired of doing what the guys want. The girls want to do something the guys hate, so Sheldon suggests clothes shopping. While waiting, Sheldon mentions he knows how to compromise because of all he does for Leonard, including still letting Leonard chauffeur him (which Leonard actually hates) though Amy is teaching him to drive. Leonard retorts that he compromises more for the often difficult Sheldon and that because of Sheldon, he does not live with fiancée Penny. Sheldon tearfully apologizes, stating his awareness of how problematic he is and how devastated he would be by Leonard leaving, resulting in both of them breaking down. They decide Leonard should move out gradually, and Sheldon agrees he can spend one night a week at Penny's, and whistle when he isn't home. Leonard spends the night at Penny's, whilst Sheldon sleeps on her couch. Meanwhile, a stressed-out Raj, once part of a team that nine years earlier launched the now to be activated New Horizons space probe, spends the day with Howard and Bernadette and then takes Howard, initially surprised that scientist Raj leans on religion, to a Hindu temple. Raj verbally berates a man who dinged his car door, but calms down on hearing his space probe is fine.
