In the aftermath of Raj and Penny's night together from which Raj believes he's in love with her, everyone seems to be mad at Raj. Although he has no intention of getting back together with Penny despite Priya having moved back to India, Leonard is mad at Raj for sleeping with his old girlfriend. Leonard turns to an unlikely source for advice about his feelings. Howard is mad at Raj for taking his supposed place as second in line (after Leonard) in Penny's loins. Howard is also mad at Raj when it comes to light that Raj fantasized about Bernadette. And Bernadette is mad a Raj for making Howard think that there was something going on between them. While Penny takes refuge away from the guys at Amy's, she contemplates her future, which includes thoughts of moving back to Nebraska since her acting career is no career at all. Ultimately, Penny and Raj need to discuss what happened, which Penny finds out is not quite what she thought. Through it all, Sheldon can only think about his leadership in the upcoming paint-ball battle against the geology department. Sheldon's actions may unwittingly bring the friends back together.

Especially with Howard and Bernadette's impending marriage, everyone, including Raj himself, is feeling sorry for Raj not having a girlfriend. The problem of Raj finding a girlfriend or one of his friends finding him a girlfriend is his inability to speak to women unless intoxicated. Penny, however, thinks she's come up with the perfect girl who at least gets around that talking issue. Emily, who Penny knows solely from her spin class, is deaf. Despite initially needing Howard to translate since Howard knows ASL - Howard who feels he needs to take poetic license in translating what Raj wants to say - Raj and Emily seem to hit it off. Raj quickly falls head over heals in love with her, and the gang believes Emily has fallen head over heels in love with Raj. However, they soon change their minds about Emily's feelings, believing that she has only one selfish interest in Raj, which makes them see Raj in a slightly different light. As the one who got Raj into the relationship, Penny feels she has to take whatever measure necessary to get him out of it, which Raj may or may not appreciate or fully understand. Meanwhile, to free up his brain for more important matters, Sheldon is leaving all trivial decisions of his life literally up to the roll of the dice.

The Beta Test Initiation

Thu, Jan 26, 201221 mins

Leonard and Penny have decided to start dating each other again, but Penny is worried that any little glitch in their second time around will stall or halt them getting back together. As such, Leonard proposes that they follow a computer software development process model, where each party directly involved in the development process provides constructive comments on the "product" i.e their relationship, so that they collectively can fix the problems before the product goes into the next phase of external testing. Penny agrees. However, the comments that each provides in and of themselves end up being viewed hypercritically by the person being criticized, and thus may halt the process in its tracks unless the critic can delve deeper into the psyche of the criticized, which in turn may have its own unintentional consequence. Meanwhile, Raj has started "dating" Siri, the voice of his new smart phone's voice recognition system. And Sheldon, with Amy's assistance, decides to host a once a week/fifty-two week video podcast on the fun of vexillology.

The Rothman Disintegration

Thu, Feb 16, 201221 mins

With Professor Rothman's retirement - or what could be considered him being forced out due to mental instability - there is a battle in the physics department between Sheldon and Barry Kripke for his lucrative office space.

Their department head will not deal with the matter and President Siebert wants them to figure it out themselves, he who doesn't really care who gets it. So Leonard, Howard and Raj try to determine a fair "duel" to see who should get the office, the activity not one that they are equally adept at, but rather one that they are equally bad at. Meanwhile, Amy gives her bestie Penny a gift to show her how much she appreciates Penny in her life. Unfortunately for Penny, she hates it and doesn't know what to do with it, especially due to its large size and Amy noticing if it went missing.

The Transporter Malfunction

Thu, Mar 29, 201221 mins

To show her appreciation for all the free meals she's had at their apartment, Penny, using money from an acting residual check, gives Leonard and Sheldon each a gift: a vintage, mint, in-the-box, 1975 Mego Star Trek (1966) Transporter, with real transporter action - apiece. They both love their gift. It has additional special meaning for Leonard since it was given to him from Penny with love. And it has additional special meaning for Sheldon since his Leonard Nimoy Spock miniature action figure would fit in the toy. However, Penny is dismayed to learn that neither Leonard or Sheldon plan on opening their respective gift to play with it since doing so would diminish its value. Later, Sheldon, hearing the voice of his Spock miniature action figure in his dreams telling him to do so, decides to open his gift to play with it. The result makes him contemplate secretly switching his now useless toy with Leonard's mint condition, still-in-the-box toy. Meanwhile, on the question of whether he will bring a date to Howard and Bernadette's wedding, a girlfriendless Raj makes a drastic decision: he will allow his parents to arrange a marriage for him. Although he really likes Lakshmi, his parent's choice of a wife for him, after their initial first few dates and thinks she may indeed be the one, an admission on her part makes Raj have to decide if marriage at any cost is worth it.

Bernadette was the one who decided that they should get married before the launch in a small but special ceremony, with only their immediate family and closest friends in attendance. The ceremony was threatened by the fact that their first and at that time only option of a civil ceremony at city hall couldn't happen due to a backlog. But Raj came up with what they all believed was an even better second option on launch day if they could pull it off. The personal issues of each within the wedding party had the potential of overshadowing what should have been Howard and Bernadette's most important day. That important day may also be shattered if Soyuz itself shatters upon launch.
