It looks like Amy and Sheldon won't be making up anytime soon as Sheldon will only make matters worse by bad mouthing his ex in the next episode of "The Big Bang Theory."

A promo video of the next episode, which is titled "The Separation Oscillation," reveals that Sheldon will air his dirty laundry about his breakup on his web series "Fun With Flags."

"Thankfully all the things my girlfriend used to do can be taken care of with my right hand," says a bitter Sheldon while filming an episode of "Fun With Flags."

"I'm gonna kill him," Amy snaps in response while watching the series online.

According to The Hollywood Hills, the synopsis reads as follows:

"Leonard is going to confront the woman he kissed on the North Sea in an attempt to set Penny's mind at ease. Also, Sheldon will film a special episode of 'Fun with Flags' after his breakup with Amy, and Bernadette will feel guilty about withholding a secret from Penny."

Season 9 of the hit CBS comedy started off with a bang as Penny and Leonard finally tied the knot while Amy officially called it quits on her relationship with Sheldon.

The season premiere picked up right where the Season 8 finale left off and Leonard and Penny finally said "I do" in a random Chapel of Love in Vegas, reports Entertainment Weekly. However, Penny couldn't seem to move pass Leonard's infidelity on their wedding night. Leonard also made the situation worst by admitting that the woman he kissed is his current coworker, Mandy Chow, who Sheldon later described as attractive and smart. As a result, their wedding night went sour, and the newlyweds returned home to their separate apartments.

Meanwhile, Sheldon persistently tried to win Amy back and ignored her wish for space. However, this only pushed her even further away from him.

Season 9 Episode 2, "The Separation Oscillation," will premiere on Monday, Sept. 28 on CBS. Watch a promo video below.
