‘Big Bang Theory’ Season 10 Spoilers: Will Sheldon Get In Trouble With The Government?

Sheldon (Jim Parsons) just made one of the biggest mistakes of his life: leaving the notebook filled with top secret quantum guidance solutions at a bar.

In “Big Bang Theory” Season 10, episode 20, Sheldon decided to get involved in Leonard (Johnny Galecki) and Howard’s (Simon Helberg) work, as well as Amy’s (Mayim Bialik) invention. He knew that he’s a key player in both studies so he took it upon himself to work really hard to impress his peers. But too much work got the best of Sheldon, and he suddenly got sick.

A few hours passed before Amy finally wakes him up from his nap. Sheldon has no recollection of what happened to him earlier that day. When he looks underneath his blanket, he realizes that he also doesn’t have his pants on. When he starts searching for his top secret notebook, he could not find it either. Luckily, Raj was able to track Sheldon’s whereabouts earlier that day and found out that he left the notebook at the bar.

When Sheldon arrived at the bar, he got his notebook back and asked everyone there to keep everything he told them the night before a secret. The bartender started deleting the solution on his blackboard. As of late, it is still unclear whether or not Sheldon’s solution will leak and if the government will find out that he wasn’t able to really keep it a secret.

Elsewhere, Bernadette’s (Melissa Rauch) maternity leave is almost over. And even though she’s excited to go back to work, she’s worried that her daughter will forget about her. Bernadette shares her thoughts with Howard, and the latter reminds the former that she shouldn’t worry because Hallie won’t remember anything since she’s still an infant.

“Big Bang Theory” Season 10 airs Thursdays at 8 p.m. EST on CBS.
