Titled "The Hot Tub Contamination," "The Big Bang Theory" Season 10 episode 5 is going to see Sheldon and Amy in the midst of disagreements even in simple things. The couple will be going through rough times right after their cohabitation debut. As things get complicated, Sheldon expressed his disappointment by threatening a break up with Amy.

Leonard (Johnny Galecki) and Penny (Kaley Cuoco) decided to intervene between Sheldon and Amy, who, after 12 hours of living together have already shown signs that their cohabitation may not last. Sheldon made the matters worse when he warned to break up with Amy if she will not agree to the bathroom schedule, according to Carter Matt.

"The Big Bang Theory" Season 10 episode 5 is all about Sheldon and Amy facing the obstacles of living together with the bathroom issues at the center of their arguments. At one point, Amy asked her boyfriend if it is okay if they placed both of their toothbrushes in one holder.

On Leonard and Penny's first night of being together alone in their apartment, Leonard and Penny started dancing in their underwear, a thing that they were not able to do for a long time when Sheldon was there, TV Guide reported. Leonard danced gracefully to the beat of "You Never Can Tell," and Penny was convinced to join him in the rhythm of "Tootsee Roll" by 69 Boyz.

Further, "The Big Bang Theory" Season 10 episode 5 will see Howard (Simon Helberg) and Bernadette (Melissa Rauch) shocked when an unforeseen visitor came to their apartment the time that they planned for a vacation. Viewers could also expect that the new episode will show how Raj (Kunal Nayyar) was able to know the gender of Howard and Bernadette's baby.

Expect more of Sheldon and Amy's petty quarrels with the new episode. It is a big question whether they will be able to survive their misunderstanding, or they will end up living in separate ways.
