Scrubs:

Turk's surgical intern, Derek, thinks he can do anything. Katie, Sunny, Howie and Denise are all getting pretty full of themselves, too. Elliot and Turk decide it's time to put them in their place. After a fun campfire story-style scare, they give the interns their assignments for the night.

Elliot is treating a repeat patient who continues to lose weight and look terrible. All the symptoms point to anorexia, but the patient insists that she doesn't have an eating disorder. Tests reveal the patient has HIV. Turk consoles Elliot telling her that HIV isn't a death sentence anymore. But the patient takes it hard, and Elliot can't help but take it the same way.

Turk's gallbladder patient seems fine, but he needs to know that everything's okay. The problem is, the patient’s a bit of a nervous pooper. Turk compromises and asks her to just break wind. Embarrassed, she refuses. So, Turk assigns Sunny the task of getting the patient to break wind. After a lot of smiling and a lot of negotiation, Sunny finally gets the patient to do the deed. The downside is that she can’t get the smell out of her clothes and hair.

Denise has a patient with fluid in her lungs and Turk tells Derek to help her out. While Denise can be as smug as the others, even she can't help but chide Derek about his cocky attitude. While draining fluid from the woman's lung, Derek sees bubbles. He's collapsed the patient's lung. Fortunately, Turk swoops in to save the day.

Derek gets served a healthy slice of humble pie when the recovering patient asks that next time she be attended to by a 'real' doctor. But when Carla makes him feel better it turns into a hot and heavy session in the hospital. Howie's patient has a psychiatric condition that makes him believe that everyone has been replaced by an evil duplicate. The patient has poisoned himself and they need to find out exactly what he took in order to treat him.

At first, Howie thinks he's cracked the case when he pretends to be in on the patient's delusion, but the man continues to lie. After a long night and several exercises in circular logic, Howie extracts the information. Turk asks how he did it. Howie says he may have slapped the patient a little. Turk believes Howie is going to do well at Sacred Heart.

At the end of the night, Turk and Elliot wonder what things would have been like if they had hooked up with each other instead of with Carla and JD. Turk also wonders if he or Elliot would always be doctors. Elliot tells Turk that she thinks he will always be a doctor, because he finds joy in whatever he does, whether it's surgery or teaching interns. But Elliot's not so sure about herself. She says she holds on to the hard things, like her HIV patient from tonight. She thinks that if she were to settle down and start a family, she’d walk away and never look back.
