What made Sheldon attracted to Amy? That’s a question that Raj asks in this week’s episode of “The Big Bang Theory” season 10. It turns out that Amy’s body had a lot to do with it, but not for the reasons you would think. In the promo, fans learn that it was more about organ donation than about love for the female form, something everyone who loves Sheldon will find hilarious.

Raj is looking for love

“The Big Bang Theory” season 10 has mostly been about Sheldon and Raj’s developments. For Raj, it’s been about finding himself, after spending the last decade as a spoilt brat living off his family’s money.

To help him understand why he couldn’t keep a girlfriend, he asked all his exes around for dinner and discussed it with them.

All his exes found the same thing in common. Raj was the guy that they needed to date to know what they didn’t want in a guy. They wanted someone who was secure in his own life, and not living off his parents. It prompted Raj to tell his father that he was going to stop taking his money. The problem was that his father paid for his rent, credit cards, and everything else in his life.

He’s had to move in with Leonard and Penny, while he figures out his finances. But before he does that, he wants to find a woman who he can love and who will love him back. That prompts him to find out how Sheldon fell for Amy and there will likely be the same questions put towards the rest of his friends.

Penny isn’t setting up a friend with Raj in ‘The Big Bang Theory’

Leonard does ask if Penny has friends that she can set up with Raj. This was something that she did for Howard, which did lead to Howard and Bernadette falling in love with each other. Their relationship has now developed into a family, with the birth of their daughter Halley.

However, Penny isn’t too inclined to setting up another friend with one of Leonard’s. She wants Leonard to find Raj a woman, as then they are ruining one of his friend’s lives instead. Bernadette may debate with Penny about how Howard has ruined her life, but she isn’t seen in the trailer.

Bernadette will have her own feelings to deal with in this week’s episode.

According to “The Big Bang Theory” season 10 episode 21 synopsis, she will leave Halley in daycare as she returns to work. She was already having second thoughts about returning to work, so she will likely feel some guilt for this next step. “The Big Bang Theory” season 10, episode 21 airs on Thursday at 8pm on CBS.
