Players in a video game known as SavageScape battle ferocious creatures. After the game ends, the testers find their boss, Vince Pearson, claiming that his hands are on fire. House walks into Cuddy's office and quits. Foreman wants to run the diagnostic department and Cuddy allows him a chance to do it. Foreman settles in House's office. Foreman discusses Vince's case with Taub and Thirteen. Foreman plans to treat him for complex regional pain syndrome with a spinal stimulation. Vince has other ideas. Having looked up his symptoms on the internet, he thinks he must have mercury poisoning and wants to be tested. Ignoring Foreman's orders, Thirteen and Taub perform the test for mercury and not the spinal stimulation. House has therapy with Dr. Nolan, who instructs him to take up a hobby. He joins Wilson in a cooking class. Foreman gives Vince news that his mercury test came out negative. Vince demands treatment for the mercury but Foreman challenges him. Taub and Thirteen administer the spinal stimulation, which results in Vince's lungs filling with fluid. Taub and Thirteen report back to Foreman that Vince has a thickened left ventricle in his heart causing pulmonary edema. Taub speculates that cocaine might be the culprit. Foreman admits to Thirteen that he has been comparing himself to House. Taub and Thirteen go search Vince's office. Cuddy visits House at Wilson's apartment. He is cooking with a Chinese classmate and they talk about Cuddy in Chinese. Cuddy wants to know if she is the reason that House left the hospital. He says no.
