“The Big Bang Theory” Season 10 will feature Brandon Jones in one episode.

On her Instagram account, cast member Mayim Bialik shared a photo with the “Pretty Little Liars” alum. Bialik captioned the photo in such a way that she wouldn’t give out details about Jones’ character. What has only been confirmed is that his role required him to wear a latex suit. In the black-and-white photo, Bialik also expressed her fondness for Jones and called him “sweet.”

Meanwhile, TV Line speculated on the possibility of Jones cosplaying as The Flash in an upcoming episode of the hit CBS TV series. After all, Leonard (Johnny Galecki), Raj (Kunal Nayyar) and Howard (Simon Helberg) all dressed up as the Scarlet Speedster in Season 1’s Halloween episode, “The Middle-Earth Paradigm.” Sheldon (Jim Parsons) has also been spotted wearing a Flash-inspired t-shirt in multiple episodes.

In other news, Jones isn’t the only new addition to the long list of guest stars who have appeared in “The Big Bang Theory.” Earlier this year, the same publication reported that Keith Carradine has been cast to play the role of Penny’s (Kaley Cuoco) dad, Wyatt. Katey Sagal will be playing Penny’s mom, Susan, while Jack McBryer will be playing Penny's brother, Randall. All three characters will be featured in the premiere episode of Season 10.

Following CBS’ announcement, Cuoco took to Instagram to express her excitement over Sagal’s casting. The two female actors worked together in “8 Simple Rules” several years ago. In the photo that Cuoco posted, the actress said that she’s happy that Sagal will once again act as her mom on television.

“The Big Bang Theory” Season 10 will premiere on CBS on Sept. 21 at 8 p.m. ET.
