Storyline

Bernadette and Howard discuss where their relationship is heading when Howard once again can't stay the night since he has to look after his mother. When Bernadette broaches the topic of them moving in together, Bernadette ultimately gives Howard an ultimatum: her or his mother. When she asked him this question, she didn't anticipate what Howard wants in a house-mate, sexual partner or not. Meanwhile, Raj's sister Priya is back in town on business. Knowing that Leonard and Priya had casual sex last time she was in town with Leonard wanting their relationship to progress further, Raj refuses to let Leonard see or speak to Priya. But Priya and Leonard do speak, and much to Raj's anger, they decide to start seeing each other. But one other person may be affected by Leonard and Priya dating: Penny. Although Penny outwardly says she is happy for Leonard, Amy, as her new BFF, wants to provide some comfort to Penny, all the while gathering some scientific data. Written by Huggo

Relationships get explored in "The Cohabitation Formulation" ep of "The Big Bang Theory"
13 October 2011 | by (Baton Rouge, La.) – See all my reviews

In this last season ep of "The Big Bang Theory": Though the sex is good, Bernadette gets upset when Howard immediately leaves in the morning in order to help his mother put on her wig and eyelash. In fact, she wants Howard to choose between her or his mom. When Howard goes home, his mother tells him she doesn't trust Bern and thinks she may have given him a disease. So Howard decides to crash at Sheldon and Leonard's apartment. When Sheldon asks why he's not at best friend Raj's place, Howard says sister Priya is staying there. Uh oh, despite Raj forbidding his sis from ever seeing Leonard again considering their sexual history, Leonard drops everything and resumes their relationship. Amy then offers to comfort Penny who says she's fine since she and Leonard broke up a while back. Meanwhile, Howard decides to cohabit with Bernadette after all. Now she'll have to shop for and wash his clothes like his mother did...Quite a lot of very funny lines that fit the characterizations of each player abound as well as some touching moments concerning Penny, Amy, and, surprisingly, Sheldon. So on that note, "The Cohabitation Formulation" ep of "The Big Bang Theory" gets a high recommendation from me.
