'The Big Bang Theory' season 10 spoilers: Sheldon writhes in pain after rebelling against Amy and his mother

The gang will sum up their chaotic Christmas break in the next episode of "The Big Bang Theory" season 10.

Reports about the episode titled "The Holiday Summation" revealed that Sheldon (Jim Parsons) and Amy (Mayim Bialik) will narrate to Penny (Kaley Cuoco) and Leonard (Johnny Galecki) how their trip to Texas went when they opted to visit his highly conservative mother Mary (Laurie Metcalf).

According to reports, Sheldon and Amy will tell Mary that they decided to move in together. Sheldon is expecting to get a scolding from his religious mother, but he will not get any. Mary will explain that she thought that Sheldon would never find a woman to marry him, which will offend her son. But Amy will later on explain that she already told Mary about their living arrangements before they head to Texas, which will further infuriate Sheldon.

To express his anger toward his mother and girlfriend, Sheldon will decide to have his ear pierced. Mary will get angry and order Sheldon to remove the earring at once, which will make Sheldon scream in agony.

Meanwhile, Howard (Simon Helberg) and Bernadette (Melissa Rauch) will have a different problem of their own as they take care of their newborn daughter Halley at home. Based on the trailer for the upcoming episode, the distraught-looking Bernadette will experience sleepless nights as they tend to their baby. The baby will also be heard crying non-stop in the upcoming episode, which will make Bernadette question their decision to have a baby in the first place.

The Futon Critic released the synopsis for the upcoming episode of "The Big Bang Theory" season 10, which reads: "Sheldon and Amy visit Leonard and Penny for the first time since the holidays and share details about their terrible trip to Texas."

"The Big Bang Theory" season 10 will return on CBS on Thursday, Jan. 5.
