The Flash is expected to make an appearance in the upcoming Big Bang Theory Season 10 and it will be hilarious.

Actress Mayim Bialik has hinted about the Scarlet Speedster’s cameo in Big Bang Theory Season 10. Bialik recently posted a cryptic message on Twitter with emphasis on the word “flash.” She also shared a photo of her and Brandon Jones, suggesting that the actor could be playing the role. Bialik posted the same image on Instragam and captioned it with more clues on the role Jones will be playing.

The Pretty Little Liars actor acknowledged Bialik’s remark and his future guest appearance on the CBS hit show.

He's sweet, he's southern and he feels comfortable in latex. Brandon Jones, we had fun having you guest star this week!

The CalTech scientists – Sheldon (Jim Parsons), Leonard (Johnny Galecki), Howard (Simon Helberg) and Raj (Kunal Nayyar) – are known to be huge fans of The Flash.  The superhero has been mentioned in numerous instances in the show. In Season 1, they were seen wearing the same The Flash costume during a Halloween party. Sheldon is frequently seen sporting The Flash t-shirt, too. In one episode, he had a discussion with Leonard if he will watch CW’s The Flash series. Viewers could expect a hilarious episode when these geeks get starstruck by the presence of their favorite DC superhero.

Meanwhile, a tension between Penny (Kaley Cuoco) and her mother Susan (Katey Sagal) will blow up in Season 10.

Big Bang Theory executive producer Steve Molaro said Penny is close to her dad Wyatt (Keith Carradine). Wyatt will be caught between Susan and Penny’s dispute this season.

Penny’s brother Randall (Jack McBrayer) will also put a lot of stress on Susan. “You will pick up on the tensions between her mother and her brother very quickly, and you get a glimpse of Penny and her dad being caught in the middle of that,” Molaro told Entertainment Weekly.

The Big Bang Theory Season 10 will premiere on September 19 at 8 pm on CBS. The hit comedy series airs on Nine Network in Australia. However, the Season 10 airing date is yet to be announced.
