The boys will have a field day, meeting their favorite Marvel superhero, in the upcoming season of "The Big Bang Theory."

Recent updates on the long-running CBS series reveal that "Pretty Little Liars" alum Brandon Jones will guest star in one of the episodes in the new installment. Very little has been teased about his role. As per TV Line, the only clue is that the actor will be wearing a latex suit in the show. This sparks speculations that Jones will arrive in the gang's apartment cosplaying as The Flash. It was noted that the red speedster is Leonard (Johnny Galecki), Raj (Kunal Nayyar), Howard (Simon Helberg) and Sheldon's (Jim Parsons) favorite superhero, based on their affinity to wearing The Flash's costume in some of the past episodes.

Sheldon has been sporting t-shirts with The Flash designs several times on the show. The other three boys, on the other hand, turned up wearing the speedster's iconic costume during the Halloween party in season 1. If Jones will really play the part of The Flash (or at least pretending to be one), the boys will likely get a kick out of meeting him. Viewers can expect that it is going to be another hilarious episode, especially when the men start "fanboying" about Jones' character.

Meanwhile, another episode to look forward to in season 10 is the arrival of Penny's (Kaley Cuoco) mother and brother. It has been teased that Katey Sagal will be playing the blonde's mom, Susan, while Jack McBrayer will be playing the ex-con brother, Randall. Penny's dad, Wyatt (Keith Carradine), will also appear with the rest of the family in the new season's premiere episode. It is expected that they will attend Penny's wedding to Leonard. The physicist will finally meet his wife's whole family. Will everything turn out okay for everyone?

"The Big Bang Theory" season 10 will premiere on CBS on Sept. 19 at 8 p.m. EDT.
