Nathan is in a locked-in syndrome state, fully aware but unable to move or communicate. House is intrigued by Nathan's condition and decides to take on the case, despite the challenges it presents.

As the team begins their examination, they discover that Nathan has a history of migraines and a recent episode of confusion. They conduct various tests, including an MRI, but the results are inconclusive. House, frustrated by the lack of progress, pushes his team to think outside the box. He suggests that they should try to communicate with Nathan using a series of yes or no questions, which they attempt through blinking.

During this process, Nathan's wife, who is visibly distressed, expresses her concerns about her husband's condition and the emotional toll it is taking on her. House, while empathetic, remains focused on the medical puzzle at hand. He instructs his team to gather more information about Nathan's past, hoping to find a clue that will lead them to a diagnosis.

As the team delves deeper into Nathan's history, they discover that he had been taking medication for his migraines, which may have contributed to his current state. They consider the possibility of a stroke or a brain tumor but find no definitive evidence.
