While the buzz around "The Big Bang Theory" Season 11 refuses to come to a halt, Season 10 is in full swing, making viewers laugh with the funny episodes. The gang of nerds is hilarious in the ongoing season and "The Big Bang Theory" Season 10, Episode 15, promises some more fun and some trick.

In "The Big Bang Theory" Season 10 Episode 15 titled "The Locomotion Reverberation," Leonard and Howard have some plan up their sleeve and they are looking to blindside Sheldon, reports Yahoo.

The two realize that Sheldon is coming in the way of their invention and slowing it down. So, they distract him by giving him the responsibility of the locomotive and tell him that he is the engineer. Sheldon is elated after hearing this and becomes motivated to finish the invention in "The Big Bang Theory" Season 10 Episode 15.

Sadly, things might not go as planned and the three would draw back their steps. On the other hand, the girls i.e. Bernadette, Penny and Amy are headed for some fun time in "The Big Bang Theory" Season 10, Episode 15. Amy and Penny take new mom Bernadette for a night out, leaving Raj and Stuart to care for baby Halley, claims Spoilers Guide.

Notably, ever since Bernadette became a mom in "The Big Bang Theory" Season 10, she has been busy with the baby and stays at home most of the time, receiving support from Howard.

During the time of her pregnancy, she had been receiving support from Raj and Stuart. The former was quite excited about the arrival of the baby, even more than Howard. Recently, he helped Howard fix Halley's nursery and before that went home with the Wolowitzes along with Stuart so that they could spend more time with the baby.

The baby has indeed become an important part of the "The Big Bang Theory" Season 10 storyline and it remains to be even in "The Big Bang" Season 10 Episode 15, and it may also develop further in Season 11.

As of now, there is no word from CBS about the next season of "The Big Bang Theory." What one knows is that after "The Big Bang Theory" Season 10 Episode 15, there are nine more episodes to come and finale will air sometime in May.
