One snap also shows Rebecca, Bert and Raj having a meal at the apartment. It seems that the newcomer won’t have a hard time fitting in with the group. It is also expected that there will be endless banter between the characters, especially from Sheldon because he has a hard time keeping his thoughts to himself.

The teaser for “The Separation Agitation” also reveals that Penny and Leonard will try to help Raj find that right woman for him. In the past, Raj has gone out with multiple women, but his relationship with them never really worked out. In the clip, Penny reminds her husband, Leonard, that she already paired Howard with Bernadette (Melissa Rauch). This time around, it’s Leonard’s job to ruin another woman’s life by introducing her to Raj.

Additionally, Raj becomes extremely curious about how Sheldon and Amy (Mayim Bialik) are making things work despite their obvious differences. When he asks Sheldon what he likes about Amy, he says that he likes her brain and body. An impressed Raj looks at Amy upon hearing this, and the latter jokes that the both of them have the same blood type so they cannot be together.

“Big Bang Theory” Season 10, episode 21 will air on CBS on April 13 at 8 p.m. EST.
