House visits Cuddy, those medical histories she gave him in hand. She tells him that they're her top two sperm-donor choices, and she wants House's expert medical opinion on which one is genetically superior. I know that Cuddy doesn't have many choices of people to help her out with this since she hasn't told anyone, but even so, is House really the right person to ask? I'd run the risk of getting a kid with a genetic disease before I'd go to him for any kind of assistance. Of course, House doesn't like either of Cuddy's choices: Donor 1284 claims to like square dancing while Donor 613 likes Mozart. This makes their potential offspring loser kids who are destined to get beaten up on the playground. Man, those sperm-donor questionnaires sure do get detailed. Cuddy, of course, cares more about her child's long and healthy life than her donors' choice of hobbies. She angrily throws a pile of files in House's lap and tells him to find her a donor who will produce a popular kid. She sarcastically thanks him for his help. Well, what did you expect, Cuddy? Class and decorum? Come on now.

Leona tries to recover despite having a really annoying roommate. The woman keeps coughing and asking for water. When Leona pulls the curtain back to help the woman out, it's not a real person at all, but a nasty, bloated body. Leona identifies the woman as her mother. With that, she wakes up and screams. I knew this was a hallucination as soon as we saw that Leona had a roommate. No one in PPTH ever has a roommate.

While House and his bad leg pace around the hallway outside the Differential Diagnosis Lair, the Cottages inside it wonder if Leona had another hallucination or if it was just a nightmare. Cameron and Foreman are sure it was the former; Chase, the latter. House enters the room and chooses option C: none of the above. Cameron starts to talk, but he shushes her by saying that he wasn't finished speaking yet. If only they could have treated Season 1 Cameron like this, I would have loved it. Now, it's just mean and kind of off-putting. House adds that Leona may have had an "atypical seizure." Then he goes back outside to pace some more. Cameron explains to the group that House does this to take his mind off of his leg hurting, because she is the House Mood Expert. House returns to the room to suggest that Leona had a flashback due to Post-Traumatic Stress Disorder. Cameron wants to know why House is so determined that this not be a hallucination. House says that would means that the heart defect they found and fixed was just a coincidence, and those never happen on this show except for almost every episode. House leaves the room again, and the Cottages go back to discussing his leg pain, since they're as bored with this patient as I am. House pops in to suggest that Leona has an autoimmune disease that makes pain -- such as the pain of an arrhythmia -- manifest itself in hallucinations. Autoimmune Disease Specialist Cameron is about to spring into autoimmune disease-testing action, but House dismisses the need for these, saying he has a way to test his theory that only takes five minutes. All they need is a PET scan and something that will cause their patient physical pain. Things are looking grim for Leona right now, I must say.
