The latest episode of “The Big Bang Theory” Season 10 revealed the reason behind one of Sheldon’s weird gestures. Fans of the long-time running sitcom know that when Sheldon knocks on a door, he does it three times and says the name of the person with each knock.
This has been a long-running gag on the show and a classic Cooper quirk. While many thought it was because of his OCD, Sheldon admits to Penny that there was an emotional reason why he does it.
The episode, titled “The Hot Tub Contamination,” saw Amy and Sheldon storming into Penny and Leonard’s apartment arguing about bathroom schedule.
When Amy suggests that they should share a toothbrush holder, the couple enters into a fight and Sheldon announces that he will find a replacement for her.
While at an ice cream parlor, Sheldon opens up to Penny and says that when he was 13 years old, he came in early from spring break when he walked in on his father with another woman.
Despite his father seeing him walk in, the two never talked about it again and he also never mentioned it to his mom.
He adds that the first knock is traditional, while the last two are for people to get their pants on. He says that since living together, he and Amy have been bickering like his parents so he’s setting her up for disappointment early so she doesn’t get hurt in the future.
Sheldon’s emotional rant to Penny stems from his fear that he will do the same thing his dad did to his mom now that he’s living with Amy.
Fans will remember that Sheldon and Amy began their experiment in living together at Penny’s place while Amy’s apartment is out of commission for five weeks.
Leonard also coaches Sheldon on how to live with Amy. With Penny’s urging, Sheldon apologizes to Amy for his behavior and decides to take their relationship to the next level by sharing a toothbrush holder with her – a big step for him.
The episode also revealed Bernadette’s baby bump for the first time. The couple’s weekend getaway was canceled because of the latter’s morning sickness and they both find Stuart and Raj secretly coming to their house using the hot tub.
Howard and Bernadette listen to Raj and reveals that he is now single, but kick the duo out when they hear Stuart saying he’s wearing a bathing suit.
The writers and producers of the CBS comedy have told numerous interviews that many secrets will be revealed in the current season. Other mysteries they need to resolve is Penny’s maiden name.
Penny’s surname before getting married to Leonard was one of the show’s longest mysteries. This season promises that fans will finally know it. Another mystery is why the elevator never got fixed.
Meanwhile, the upcoming episode, titled “Fetal Kick Catalyst” suggests that the episode will center on Bernadette and Howard’s baby.
Next week’s episode will return to the regular Thursday timeslot now that Thursday Night Football on CBS is over.
The network hasn’t released an episode synopsis for the October 27 episode yet. However, with the previous episode revealing Bernadette’s baby bump, it could mean that the unborn baby will be the star of the episode.
Game & Guide reports that the Wolowitzes will finally feel for the first time their baby kicked and this should be an unforgettable experience for the couple.
Speculations also say that Amy and Sheldon will have a brunch in their apartment as an attempt to work out their co-habitation issues.
Reports also say that Kaley Cuoco’s Penny will be out of town for next week’s episode to attend a comic convention, but the details still are not confirmed.
