Ep 20. Simple Explanation

House season 5 episode 20, named "Simple Explanation," centers around the case of a young woman named Greta who collapses suddenly and is rushed to Princeton Plainsboro Hospital. She had previously been admitted to the hospital several times with various symptoms, but no diagnosis had been made.

The team is struggling to figure out what is wrong with Greta, and House becomes obsessed with the case, spending hours poring over her medical file to find a diagnosis. Meanwhile, Thirteen is dealing with her own personal issues, as she is grappling with the news that she has Huntington's disease.

As the team continues to search for answers, House's behavior becomes more erratic and he begins to clash with his colleagues. He becomes convinced that Greta has a rare condition called Cushing's disease, which causes excessive production of cortisol in the body. However, the rest of the team is skeptical.

As the case progresses, the team faces a number of obstacles. They discover that Greta is pregnant, complicating her treatment options, and House's behavior continues to become more erratic. Thirteen, who is struggling with her own mortality, becomes increasingly frustrated with House's behavior and his lack of consideration for the rest of the team.

As House becomes more convinced that Greta has Cushing's disease, he begins to use increasingly drastic measures to prove his theory. He orders a series of invasive tests without Greta's consent, and when the team questions his methods, he dismisses their concerns.

In the end, the team discovers that House's diagnosis was correct and Greta does indeed have Cushing's disease. However, House's methods have put him at odds with his colleagues, and he must confront the consequences of his actions.

"Simple Explanation" is a gripping episode that delves into not only the medical mysteries that the team at Princeton Plainsboro Hospital faces, but also the personal struggles that each character is dealing with. With stunning performances from the cast and a tense, suspenseful storyline, this episode is a must-watch for fans of House.
