Personal Storyline


The episode opens with Drakken and Shego haven stolen nanotronium, the smallest, most powerful energy source in the world. Drakken's glory is cut short when Kim swings onto the hovercar and snatches the nanotronium away. Ron, meanwhile, is tangled in his grapple line. Shego fights Kim to get the mini energy source back. In the fight, Kim and Shego hit the hovercar's steering levers, causing it's speed to increase. Ron manages to climb aboard and pick up the nanotronium. Rufus then hits the steering levers to cause the hovercar to spin. Kim and Ron jump off while Drakken and Shego continue their dizzying ride. Ron feels proud of himself until he notices he lost his pants again.

At the mall, Kim tells Monique it isn't a big thing that she and Ron have been dating for six months, but Monique (who calls it a half-iversary) thinks different. Kim does have a gift for Ron thought- a belt made by Wade and reinforced with flexible titanium so that Ron's pants would no longer be an issue. Ron arrives and the two are about to go to Kim's mother's hospital to cheer up the kids there. Before leaving, Kim gives Ron the belt. Ron says he doesn't need it, but reconsiders after a passing cart rips away his pants.

Shego comes into the lair to discover Drakken still in his pajamas, looking for a piece of paper on which he wrote a 'foolproof' plan that came to him in his sleep. Drakken can't find the paper and is unable to remember what he was dreaming. On the t.v, a scientist unveils his invention- the M.R.M or Memory Recovery Machine, which can restore anyone's lost memories. Drakken decides to steal the device for himself to remember his plan. To Shego's dismay, he starts using cards to keep track of his ideas.

At the hospital, the kids are happy to see Kim, Ron, and especially Rufus. Meanwhile, Drakken and Shego break into a nearby lab and grab the M.R.M, but before they can leave, they are discovered by the inventor. Rufus is showing off for the kids when they hear an explosion caused by Shego. While Kim fights Shego, Ron tries to grab the M.R.M away from Drakken, but they drop it and the power cell falls out. Drakken then shoves the power cell in backwards. Kim grabs the M.R.M away from Drakken just as it explodes. Drakken and Shego escape while Ron asks Kim if is okay, only she doesn't know her own name. With the power cell in backwards, the M.R.M has given Kim complete amnesia.

At the Possible house, Kim's parents plan to restore Kim's memories while her brothers take advantage of her loss of memory by dressing her funny, much to her parents displeasure. Kim's father shows her a video containing compressed version of Kim's life as well as clips from Kim's least favorite show, Captain Constellation.

With Kim's memories of crimefighting gone, Shego takes advantage of the situation and begins a series of heist. She returns to the lair to discover Drakken sleeping. Slamming the door, Shego wakes Drakken up. Drakken has recalled the plan from his dream and has written what he remembers down on a card. Shego finds the information on the card baffling: sandwiches, trains, mind-control, and green men.

Ron arrives at the Possible house the next morning to pick up Kim, who has recovered most of her basic memory. To Ron's dismay, Kim doesn't remember they are dating. Ron tries to prove to Kim he's her boyfriend by giving her a bouquet of flowers, but she mistakens it for a salad.

At school, Ron gives Kim a tour of the school and the run into Monique. Ron tells Monique Kim's making progress, but she still doesn't recall relationships she has. To Ron's surprise (and displeasure), Kim instant remembers meeting Monique.

Shego comes back to the lair from her latest heist and finds Drakken in his lab, concentrating his leftover brainwashing shampoo into a mind-control serum for the final phase of his plan. Despite Drakken saying the plan is foolproof, Shego thinks it's anything but.

Ron takes Kim to Bueno Nacho, where she recalls everything there. Ron is upset that is Kim remembering everything except the fact that they are dating. Ron shows Kim a photo of them on their first date (at the prom). Kim then recalls when Ron called her about his dream where they where at the dance and Kim melted. She then believes that Ron was dreaming that they were dating. Ron attempts to correct Kim when her watch starts beeping. When Kim asks why it was doing that, Ron reintroduces her to Wade, who tells them about Shego's crime spree. Kim suggests they call the proper authorities, but Ron grabs her wrist and explains about Kim's crimefighting on their way.

Kim and Ron arrive at the store Shego just robbed. Despite her remembering Shego, Kim doesn't recall how to fight her, so when Shego attacks, Ron intervenes. While Ron dodges Shego's attacks, Kim signs an autograph for one of her fans.

Back at school, Wade gets Shocked & Horrified Ron had to battle Shego alone. Wade has Kim participate in cheer practice to help her remember her fighting skills. Ron tells Kim to ignore Bonnie's remarks and she'll be find. Kim does pretty sloppy at first, causing Bonnie to comment that she knew this would happen when she started dating "Nacoboy". Ron claims that he is Nacoboy, but Kim remembers what Ron told her and ignores Bonnie, frustrating Ron. Determined to show Bonnie, Kim recalls her cheerleading skills and does the routine perfectly.

In the mountains, Drakken and Shego are watching a passing train. Thanks to an emergency caused by Drakken, everyone on board jumps out. On the train, they discover thousands of sandwiches for hungry soldiers. Drakken plans to add his mind-control serum to the sandwiches, allowing him to control the entire military. Before Drakken can add the serum, Kim and Ron appear. Kim recalls everything except one little detail Ron has tried everything to restore. Due to Drakken's foolishness, the train will explode. Shego abandons Drakken. Kim tells Ron to fix the engine while she deals with Drakken. Drakken changes his plan, insteading of using it on the sandwiches, he'll use it on Kim.

In the engine room, Ron and Rufus try effortlessly to fix the bypass, but no luck. On top of the train, Kim takes the mind-control serum from Drakken and ducks as the train goes into a tunnel, causing Drakken to fall off. Kim heads into the engine room to shutdown the engine, but is blocked when the steam vent busts. Kim tells Ron to close the vent. Ron throws his new belt over the pipe. The flexible titanium allows him to squeeze the vent shut. With her way clear, Kim is able to shutdown the train. Without his belt, Ron's pants instantly fall off. Seeing this, Kim recalls all the times that Ron has lost his pants. Strangely, this allows her to recall her final missing memory- she loves Ron Stoppable. As his girlfriend hugs him. Ron says "Now THIS is a memory". Elsewhere, Shego is hunched over Drakken with a card of her own: "Dr. D fails".

Ending Credits: Kim and Ron are watching Captain Constellation while Kim wonders why she knows every episode, yet she hates the show, not knowing her father had her watch three compressed seasons while her memory was returning.

Running Gags

Kim eventually remembers everything, except that she and Ron are a couple who are dating each other. Absolutely nothing convinces her of that fact, until he loses his pants for the third time, triggering her full memory.


  • This episode first aired in New Zealand on July 4th, 2007.
  • In this episode, Ron loses his pants, not once, not twice, but three different times:
    • After the first mission.
    • Right after Kim gave Ron the reinforced with titanium half-iversary gift of the belt.
    • Right after Ron took off the belt to cut off the steam, after which Kim remembered they were dating.
  • This episode is the first in which Kim tells Ron she thinks she loves him.
  • The little girl, Kaitlin, who asks for Kim's autograph as her "biggest fan" was named for and voiced by a Real Life seven year old girl diagnosed with a brain tumor as part of the Make-A-Wish Foundation[1].

Production Information


  • This episode is stated to takes place six months after the events of So the Drama, which likely took place in April or May, and therefore would place this episode in October or November. However, Kim had her original mission outfit in "The Cupid Effect", which, being set in February, would obviously take place after this episode.
  • In the pic that Ron shows Kim at Bueno Nacho to help her remember that they are dating, Kim is wearing earrings and her dress is not destroyed at the bottom like it was in the movie So the Drama, and the episode Ill Suited.
    • It is likely the photographer had the pic photoshopped.
  • Two of the flashbacks in which Kim remembered Ron losing his pants originated from the episode Exchange. Kim, however, was never there, so she could not have remembered those incidents.
    • Another flashback of Kim remembering when Ron losing his pants originated from Sick Day, when she was sick at home, and was not with him, so there is no way that she could have remembered the "Little pants related mishap", when he was bungee-cording down into Drakken's lair so that he could recover the stolen Ray X.
  • After Kim fails to stop Shego, Wade suggests that cheerleading practice might help Kim remember how to fight. But Wade should have years worth of footage of Kim fighting during missions, yet does not think to mention or show them to her.
  • Ron thrusts Kim, who is suffering from memory loss, into a mission where he expects her to fight Shego, but does not think to check whether Kim remembers how to fight at all until after Shego starts attacking.
  • Ron really should not have had so much trouble convincing Kim that they were dating. If nothing else, the people who did not help him, should have.
    • There should have been plenty of material in the home movies covering the period where Ron and Kim were dating. But judging from Kim's reaction when Ron first mentioned it, the implication was that her parents did not even see fit to inform her.
    • Ironic that Monique made such a big deal about Kim and Ron dating for six months, yet would not help Ron convince Kim. Very fortunate then that Kim did not meet someone she was interested in dating while she was out shopping with Monique.
    • Kim's refusal to take Ron at his word was likely influenced by the fact that no one else close to her supported Ron's claim. And considering how easily Kim fell victim to Shego's lie, Kim could just as easily have been talked into thinking she was evil.
    • While the preferred method was allowing Kim to remember on her own, having a boyfriend should have taken some sort of priority over that. Especially since, just as with crime-fighting, she did not believe it initially. What everyone but Ron failed to appreciate was that Kim being told Ron was her boyfriend, by multiple sources, was far more important than her accepting it right away. Kim did accept that she alone had memory loss, so she eventually would have accepted that if enough people were reinforcing an idea, it was likely true.
