Season 10 of the multi-awarded sitcom, "The Big Bang Theory," continues, and Leonard and Howard will try to divert Sheldon's attention from their work in the series' next episode.

The synopsis for the upcoming 15th episode, titled "The Locomotion Reverbiration," mentions that the two characters, played by Johnny Galecki and Simon Helberg, respectively, will attempt to veer Sheldon, (Jim Parsons) away. The reason is that Sheldon slows the progress of their guidance system.

To divert Sheldon's attention, Leonard and Howard will reportedly give Sheldon tickets to "a historic railway." Meanwhile, Penny (Kaley Cuoco) and Amy (Mayim Bialik) will have a girls' night out with Bernadette (Melissa Rauch), which leaves Raj (Kunal Nayyar) and Stuart (Kevin Sussman) in charge of taking care of baby Halley.

To add to the buildup of the next episode, which airs on Thursday, Feb. 9, the episode teaser showed Sheldon holding the tickets to the locomotive event and hugging Leonard with joy and excitement. The video, however, also showed Sheldon repairing an engine, which seemingly made a spark inside their living room earlier.

In last week's episode, titled "The Emotion Detection Automation," Sheldon, who is known to be insensitive to other people's feelings and is weak in recognizing social cues, took baby steps toward improving on his area of weakness. He creates the emotion detector after being inspired by Raj's breakup. Raj, on the other hand, had no clue why his relationship led to a bitter ending, so he organized a focus group discussion with his ex-girlfriends to ask them what was wrong with him.

Sheldon's new machine, which determined people's true feelings by recording their heartbeat and breathing patterns, spelled trouble for Leonard and Penny when the former said he was cool living with the latter's brother who happened to be a drug dealer. The machine, in turn, detected Leonard's true feelings about the whole setup, which was anger.
