In the real world, Kelso says that Doug stayed after his shift, so he has to leave. Kelso orders Ted to take one last body to the morgue, and Ted puts out his back attempting to do so -- turning into a hunchback! Clever! Elliott asks Carla and Turk about the tests they ordered for her patient.
Back in fantasyland, Turla, JD, and Elliott have arrived at the Potion Shop. They find The Todd, who is The Fairy Todd Something, flying around in there, and they have to wait until he's finished before they can get their potion. The Todd uses magic to remove the male shop owner's clothes, and then demands a Fairy Five.
Back in the real world, Carla is demanding that the lab process Elliott's test results before The Todd's, and The Todd steps aside. Carla rushes back with the test results. Elliott is disappointed to find out that they are negative, since that means she still doesn't know what's wrong with her patient. She announces: "I've gotta page him."
In Fantasy Land, Elliott sends a messenger pigeon up into the air, and summons what JD calls "the bravest, most handsome knight that any of them had ever seen." The knight removes his helmet, and of course, it's Cox, complete with an Inigo Montoya style mustache. Elliott explains how she can't beat the monster, and Cox says that's not possible. He marches into the cabin where the handmaiden lies, and proclaims to the monster: "My name is Percival Cox. You're killing my friend. Prepare to die." Cox takes a swing at the monster and cuts it in half, but it regenerates. Turla says that he doesn't know what's scarier: the monster or that scary old lady. Just then, Jordan (looking like Carol Kane) pops out of the bushes. In real life, Jordan (with a green facial mask on) pops her head into Jack's bedroom and says that it's bedtime.
Cox pops back into Jack's room and asks if he wants to hear the rest of the story. Jack, of course, does. Cox picks up with the Knight (himself) getting his ass kicked. I'm guessing they spent so much on the smoke monster effect, they had to show that scene twice. Cox the Knight gets tossed out of the cottage and says that the monster cannot be slain by any sword. They must go to the Forbidden Forest and find the golden ring. Back in real life, Cox tells JD and Elliott that they have to find the diagnosis instead of treating the symptoms, by going back to their textbooks and case studies. And, Cox adds, JD has to remember what he heard when he wasn't even listening. JD doesn't even know what that means.
