As Eliot begins to plan her wedding with Keith, J.D. continues to question his true feelings for her. In an attempt to ease his best friend’s mind Turk takes him to a surgeon’s convention in Phoenix, but the plan backfires when J.D. runs into his ex-girlfriend Kim and comes face to face with the unexpected. Meanwhile, Kelso and his cronies party it up at the convention while unknown to him, the Janitor takes on the role of chief of medicine back at Sacred Heart.

When Eliot’s engagement ring doesn’t fit, Keith agrees to a “redo” in which the particular Doctor plans her own engagement. Carla, Jordan and Eliot’s sorority sister Melody gather to help plan the “surprise.” Meanwhile, the men of Sacred Heart are suffering from too much talk and not enough action as J.D. continually gets shot down by Melody, Turk and Carla have not been intimate since their baby was born and Dr. Kelso’s cold showers. In the end J.D. realizes that he might still have feelings for Eliot.

J.D. feels a little left out when Eliot’s wild sorority sister, Melody comes to town. Not able to deal with being the third wheel he turns the girls against each other in the hopes that he will once again be Eliot’s priority friend and, if he is lucky, that he might get to “mash” it with Melody. Meanwhile, Turk and Dr. Cox go head to head when they disagree over whether or not a patient requested surgery is necessary. Elsewhere, Carla discovers an unlikely ghost haunting pediatrics in an attempt to keep it clean. In the end one of Sacred Hearts own will be considering a marriage proposal.

In a unique twist, J.D. turns his narrating duties over to Ted, Todd and Jordan — as this episode focuses on the lives of the supporting players at Sacred Heart Hospital. Ted juggles fantasies in which he has a full head of hair and a reality where he is helping the nursing staff fight for a raise; Todd meets his future son and helps Turk preserve his reputation and Jordan puts aside her knack for causing misery to help Elliot and Keith’s relationship.

After saying goodbye to Nurse Roberts, the Sacred Heart staff institutes some of her lessons into their lives. Though Carla thinks they’ve all forgotten, Dr. Cox takes time to reflect on his purpose; Elliot opens her heart to Keith; and J.D. and Turk learn compassion.

Nurse Roberts’ condition begins to worsen and each of the staff members deal with the possibility that she may not make it in their own, individual way. Elliot and Keith cope by staying busy together, J.D. and Turk deal through childish behavior, and Carla finds comfort in an unlikely source. But as one life may end, Dr. Cox and Jordan welcome a new life and J.D. tries to sell himself as the best choice for the baby’s godfather.

Turk hires a hot nanny and though both Turk and J.D. are pleased with her, Carla is not. Elliot and the Janitor due their best to cheer up a dying patient, but Dr. Kelso isn’t thrilled with their enthusiasm. Meanwhile, Nurse Roberts and Dr. Cox debate whether or not “everything happens for a reason”.

Unbeknown to Dr. Kelso, J.D. and Turk try to beat the system to treat the Chief’s uninsured friend. Elsewhere, the Janitor blackmails Carla with a case of mistaken dog identity. Meanwhile, Dr. Cox tries to convince Eliot that a reformed drug addict isn’t quite clean. All the while the entire staff is condemned to wearing dirt brown scrubs when Kelso suspects a clothing thief in their midst.

The day has come for Private Brian Dancer to be released from Sacred Heart, but when the military informs him that his injuries are too severe to return to service he spirals into a state of depression. Eliot, J.D. and Turk rally around him to boost his spirit. Meanwhile, Dr. Cox informs Carla that her jokes are just not funny.

While helping a patient regain his memory, the staff at Sacred Heart stir up some memories of their own. J.D, Elliot, Turk, Carla, Dr. Cox, Dr. Kelso and Janitor take a trip down memory lane in this unique look back on six years of ‘Scrubs.’
