This week’s episode of Scrubs, “Our Mysteries,” was by far the best episode of season nine. Unfortunately, everything great about it will be gone for the rest of the season.

In this episode, J.D. is getting ready to leave the medical school (where he’s going, I’m not sure). Lucy is, of course, worried about how she will survive without her mentor guiding her. J.D. still assures her that he’ll be in her head and her heart.

Only, when he says this, he has to touch her head and her stomach, because apparently one time he touched a female student’s heart and was forced to watch a video called “Boundaries.”

Lucy mentions that teacher evaluations are this week, and J.D. is excited to find out what his students will say about him. Dr. Cox, on the other hand, could not care less about the opinions of his students. Instead, he is busy preparing them for their last examination of the quarter, which is drawing blood.

Meanwhile, Denise and Drew bond over watching Dr. Cox yell at a pudgy student. What a sick couple.

Then comes the best moment so far of season nine, in which J.D. puts on a hilarious slideshow of moments of him in the classroom (“Powerful stuff, huh?”) and finishes the semester off with a speech. Unfortunately, he can’t get the balloons to fall like he planned at the end of it.

As expected, J.D. comes out number one on teacher evaluations. This reminds me of an episode in season eight, in which J.D. was rated the best doctor on Ratemydoc.com—all proof that it’s impossible not to love this guy. I particularly loved J.D.’s comparison of the teacher evaluation results list to the cast list from his summers at theater camp.

In fact, J.D.’s evaluations are all stellar, and the kids can’t say enough good things about him—except for one that calls him “needy, desperate, light on medical knowledge, heavy on Broadway trivia.” This particular evaluation also says that he “doesn’t care about teaching, he just wants people to like him.” Needless to say, J.D. is distraught and ready to find the perpetrator who criticized him.

J.D. and Turk decide to be like the “interracial Hardy Boys” to solve the case. Cue J.D. imagining the pair with magnifying glasses on the covers of books.

In the meantime, Drew has the pleasure of meeting Sonny, who appears for the first time this season. Sonny is still the overly happy, obnoxiously positive girl she has always been, but for some reason, she doesn’t have that incredibly high-pitched voice she used to have. I’m not sure what happened to her voice, unless they’re planning on making her a larger character now and understand that viewers might not have been able to take her nails-on-a-chalkboard voice in such large doses.

Anyway, Denise agrees to go on a double date with Drew and Sonny and her boyfriend. Still, she intends on calling it off at the last minute.

While he is busy worrying about someone who said that he’d do anything for people to like him, J.D. allows Lucy to butcher his arm while trying to practice drawing blood. Lucy has a horrible time mastering the technique and asks J.D. to be her blood buddy at the test. Of course, he accepts.

J.D. and Turk use the handwriting of the anonymous evaluation and determine the suspect to be Barry Freedman. Unfortunately, Freedman quit med school at the beginning of the semester, and Dr. Kelso has been using his dorm as a place to hook up with women.

Later, Dr. Cox overhears Denise telling Sonny that Drew doesn’t want to go on the double date. He convinces her that Drew is gaining power in their relationship, and he scares Denise into making Drew go on the date anyway. When they get there, Denise and Drew actually discuss their relationship status. Denise lets Drew know that they actually are in a relationship, and she decided that they have been for about a month now.

Finally, after J.D. draws all of his students into the lecture hall and gives them the fifth degree, Dr. Cox admits that it was he who wrote the evaluation. He tells J.D. that he is too busy holding everyone’s hand instead of actually teaching them.

J.D. takes the message to heart—when it is time for Lucy to have her examination, J.D. is nowhere to be found. He finally lets her learn on her own, and she actually succeeds.

At the end of the episode, J.D. and Turk gather all the students in the quad and have everyone “eagle” (one person jumps on the other’s back and they run around with their arms open wide) together. What a beautiful last moment for J.D. and Turk to spend together as teachers.

This episode had so many hilarious moments, but unfortunately, they were all because of J.D.

Next week, when he’s gone, I really wonder if the show is going to be even half as good.
