Episode 4 – The Wiggly Finger Catalyst (504)
After playing Dungeons & Dragons with the others, Sheldon decides to let the game’s dice make trivial decisions for him from now on, so his mind is freed up for other, more important things. Although his theory proves useful as he is being able to complete two important research papers very quickly and is “close to figuring out why the LHC has yet to isolate the Higgs boson”, he ends up having to eat things he wouldn’t normally eat and even grows a moustache.
Meanwhile, Penny sets Raj up with her deaf friend, Emily (Katie Leclerc), for whom his selective mutism is no longer an issue. He immediately takes a liking to her, although he requires Howard as a communicator at first. The two continue to see each other and Raj learns sign language to be able to talk to her on his own. After Howard tells Penny that he buys her all kinds of expensive things (such as diamond earrings) and even leased her an expensive car, they begin to suspect Emily is taking advantage of Raj. Sheldon, who is revealed to be a notary public and has helped Raj on several occasions with his banking documents, tells them that he is actually much wealthier than he lets on, stating that the Koothrappalis are “about halfway between Bruce Wayne and Scrooge McDuck”. Unable to reason with Raj or Emily, Penny informs Raj’s parents about his girlfriend, who then threaten to cut off his allowance if he does not break up with her. Raj tells them that he chooses love and then informs Emily about his decision and also tells her that they are going to have to return her car and all the jewellery he bought for her (including a very expensive necklace from Cartier). Emily then dumps him and leaves a heartbroken Raj behind. He then commiserates at the Cheesecake Factory with his friends. When Penny brings the bill, they leave him behind with it, as they now know just how much money he has. In addition, Penny tells him that he better not cheap out on the tip.
