Carla needs courage to have a child with Turk even though she can't stand babies. Elliot needs the brains to handle speaking in a medical seminar. And J.D, well, he just wants to get home...

J.D., Turk, Elliot and Carla are accused of neglect and must face an interrogation by Cox and Kelso, when a patient unexpectedly dies during their watch.

When a potential new girlfriend enters J.D.'s life, Elliot offers J.D. relationship advice and tries to help break his bad habit of ruining romantic moments by uttering really inappropriate things. Meanwhile, Jordan and Carla each have problems with Dr. Cox, and Turk joins the hospital air band.

When Carla begins to feel old, she drags her friends to a college club and decides to take a fertility test, among other things. And while all of J.D.'s friends love Julie, they begin to worry that J.D. is going to ruin the relationship after he begins saying his thoughts aloud.

The Sacred Heart staffers each try different ways to take their minds off the fact that a favorite patient, Mrs. Wilk, has to undergo an extremely risky procedure. While J.D. and Elliot try to get lucky in love, or maybe just find themselves booty calls, Dr. Cox finds a new drinking buddy in the Janitor, and Carla encourages Turk to fight for a female-friendly hospital gym.

J.D.'s dislike for and resentment towards intern Keith increases to the point where J.D. tries to get him dismissed from Sacred Heart, but the plan backfires. Elsewhere, Elliot and Turk misplace their patient's deathbed statement to his children; and the Janitor attempts to keep a pet bird in the hospital without Dr. Kelso knowing it.

Grief counseling is offered to Mrs. Wilk, whose condition has worsened considerably. As she comes to accept her fate with help from a quirky therapist, J.D. and Dr. Cox surprisingly turn to each other for support as they face losing their favorite patient. Elsewhere, Ted and the Janitor team up to give bitter Kelso a taste of his own medicine, and Elliot's relationship with Keith changes.

Dr. Cox is named the best doctor in the area in a leading publication. He lines up the hospital staff and requires them to acknowledge this. Dr. Cox subsequently struggles to treat an unnervingly rude and haughty patient who is a friend of Dr. Kelso's. Because of Kelso's personal connection, he declares himself unsuitable to treat her. After struggling to conceive, Carla, who has already taken a fertility test, questions Turk's fertility. He is unwilling to have himself tested, so she tries to "spermjack" him to find out. Eventually, he capitulates and learns that he is not shooting blanks. Elliot finds out J.D. doesn't like her new boyfriend, intern Keith. The other interns start complaining that Keith is being treated preferentially because he is sleeping with her. J.D. is initially unwilling to support Elliot, but finally changes his tune. To keep in touch, Zach and Turk have outfitted each other with radio watches. J.D. gets disgusted with his at one point and ditches it in the trash. The janitor hears it when he tosses the trash can in which it was disposed. For a short time, he uses it to carry out some practical jokes on J.D. But J.D. figures this out and manages to reverse the jokes by sending the janitor into the freezer and locking him in.

When Dr. Cox scoffs at reading lines with a patient preparing for a play, J.D. urges his fellow doctors to do special, unconventional things for their patients. But when J.D. scores a date with a hot babe who loves his hair, he's not sure he can shave his head for a woman undergoing chemo. Turk and Carla attempt to eliminate all stress to better their chances of conceiving, but Turk has to compete for a surgical resident spot and Carla loses Dr. Kelso's VIP patient. Meanwhile, Elliot showers Keith with stupid gifts.

Turk finds out that Carla is pregnant.

When J.D. rearranges his schedule to allow himself more time with Turk, Turk secretly resents hanging out with J.D. because it interferes with his own "Turk Time." Meanwhile, Cox and Jordan go on a double date with Elliot and Keith, and Carla covers for Kelso at work as he grieves for his dead dog. Later, a patient almost dies after giving up part of his liver for his brother, and the hospital staff learns about making sacrifices for the people they really care about.

J.D. is forced to show his brother Dan some tough love when he shows up in town. Carla and Turk pick baby names. Dr. Cox realizes the consequences of making negative comments about Kelso's son.

The hospital is seen from the perspective of The Janitor, who's out to prove he can make a difference after getting rid of J.D. for the day. Also, Turk sees his "blackness" called into question by Dr. Cox, and Elliot's intern's mistakes begin to frustrate her.

J.D. accidentally runs into Dr. Cox in a store, who both then run into annoying former suicidal patient Jill Tracy. Meanwhile Elliot and Carla do a little investigating and find out that Todd hasn't actually slept with anyone in the hospital - they jump to conclusions about his sexuality.

Carla persuades all her coworkers to rally around a despondent Dr. Cox, after three of his patients die because of his mistake. Everyone participates except J.D., who thinks his selfish reaction crossed the line.

Dr. Cox returns to the hospital, but Elliot quickly learns the hard way that he's still his same old obnoxious self. And Carla forces Turk to also give up the things she has to give up while she's pregnant.

J.D. challenges a urologist's assessment on a consult for a patient who might need a risky surgical procedure, feeling that she's playing it safe professionally and personally, since he also starts to fall for her. Along the same lines, Elliot considers breaking up with her boyfriend/intern Keith for being too weak, especially when he's being picked on by Dr. Cox.

J.D. tries to plan the perfect date for Dr. Briggs, but Elliot keeps getting in the way. Elliot plans a baby shower for Carla while two other women also discover they're pregnant.
