The Big Bang Theory is going well with its tenth season. In fact, ten seasons after airing, it is still one of the most talked-about television sitcoms to date.

On the Big Bang Theory season 10 episode 18 titled "The Escape Hatch Identification," Raj (Kunal Nayyar) lives with Leonard (Johnny Galecki) and Penny (Kaley Cuoco). Leonard and Penny's new roommate takes over Sheldon's old room.

Apparently, Raj's parents have cut him off so he can no longer afford his luxurious lifestyle. At first, Leonard was scared of telling Sheldon (Jim Parsons) that he and Penny have taken Raj under their wing.

Eventually, he will have the courage to confess. To his surprise, Sheldon actually had a carefree response.

Instead of a witty retort, Sheldon couldn't help but observe, "I think it's nice that you're taking whatever medication is clearly giving you." Most shockingly, he also revealed that he is fine with Raj is staying in his old room.

He said, "If you're implying that I have some problem with him moving into my old room, you're wrong." This comes as an unexpected surprise to most fans.

The bizarre reaction did not only shocked the fans; it shocked Leonard as well. In fact, he was so puzzled by Sheldon's reaction that he decided to reach out to his mother for advice.

Leonard's mother, Beverly (played by Christine Baranski) is a psychiatrist. On another note, Baranski has gotten multiple Emmy bids just for this scene-stealing performance.

Many fans believe this could finally be the episode that will win her a Best Comedy Guest Actress - fingers crossed. According to TV Line, Christine Brasanki's character will help Sheldon unravel the mystery surrounding his non-infantile reaction to Raj's change of address.

What exactly is happening on Sheldon? Fans can only wait for the Big Bang Theory season 10 episode 18.

The Big Bang Theory returns to CBS on March 9, at 8/7c. Keep checking back on Auto World News for more updates.
