An episode that consists of two 15-minute unrelated stories:
In "Sick Day," the Tweebs catch a nasty cold, which gets passed along to Kim. She still insists on taking a job guarding "Ray X", but fails to stop Drakken and Shego from stealing it. With Kim's mom insisting that she stay in bed, it falls to Ron and the Tweebs to retrieve the device.
In "The Truth Hurts," Kim and Ron rescue a captured scientist. Unfortunately, along the way they get hit by Dr. Drakken's "Truth Ray", forcing them to blurt out their honest thoughts. The effect will wear off in a few days, but until then they're stuck with a rather awkward situation, especially Kim as her father's supervisors from the Space Center come over for dinner.
"Sick Day" contains the following tropes:
- Bedhead-itis: Almost everyone who catches a cold (Kim, Shego, and Ron) ends up with frazzled hair.
- Big Sister Instinct: When Kim sees that Jim and Tim have been captured by Drakken while attempting to retrieve Ray X, she drags herself out of bed despite still being sick to rescue her brothers.
- Continuity Nod: With Shego sick Drakken tries looking for a substitute; one villain he definitely doesn't want to team up again with is DNAmy.
- Evil Lawyer Joke: Hank from the temp agency brings up his law degree when Killigan asks him if he has any previous experience in villainy; Killigan decides it's "close enough" .
- Green Around the Gills: Ron comments that Shego looks green, and quickly amends it to greener (than usual).
- Illness Blanket: At one point, Kim is sitting at the kitchen table wrapped in a blanket while eating soup. Later, both she and Ron are sitting in the living room with blankets draped over them.
- Ill-Timed Sneeze: Drakken and Shego take advantage of Kim's sneezing to sneak in and grab the Ray-X device; however, Kim spots them before they can escape with it.
- Infection Scene: When Kim gets sick the following morning after the tweebs get sick, Wade "helpfully" illustrates this by showing camera footage of the "germ trail": showing that when she went to give her twin brothers tissues, Jim placed his hand on the table where she unknowingly put her hand on and then covered her mouth with it, unwittingly infecting herself.
- Ironic Echo Cut: When Kim hopes she doesn't get sick from the tweebs, she wakes up the next morning bedridden, wondering how she got sick. Wade was able to catch the action beforehand: when Kim was giving her brothers tissues when they were eating their chicken soup on the kitchen table, Jim placed his germy hand on the table after covering his sneeze, and Kim unknowingly put her hand on the infected surface, then covered her mouth with it, causing her to unwittingly get infected herself.Kim: Well, at least he covered. I do not want to catch this. [the following morning, she is bedridden and sick] How did I catch this?!
Wade: We can go to the tape. [plays back the scene]
Kim: What?
Wade: I've enhanced the germ trail. [the video shows Jim placing his germy hand on the table, which Kim then touches]
Kim: Eww. [the video then shows her covering her mouth with the germy hand]
Wade: Woop, there it is!
Kim: I don't even want to know how you got that. - Irony: Ray-X, which everyone has been going out of their way to avoid being hit by due to them assuming the blast will result in negative consequences, turns out to cure the common cold that they've all been afflicted with. Ron even lampshades this.
- Out Sick: Kim initially guards Ray X despite her cold, but later her mom makes her stay home and rest. Meanwhile, Shego, who caught Kim's cold during their fight, calls in sick.
- Punch-Clock Villain: Ron encounters Shego as he retrieves Ray X. She just stands there, not lifting a finger to stop him — she's not incapacitated, but she's called in sick and is off the clock.
- Series Continuity Error: The Ray X was built to cure the common cold, something which intelligence-enhanced Rufus already did back in "Naked Genius".
- Of course, it may be that Drakken's abduction of Ron during that conference prevented Ron/Rufus from actually sharing that information with anyone.
- "Shaggy Dog" Story: After a series of adventures in which the Ray X generator gets stolen, almost retrieved, and finally destroyed, with everybody involved catching a cold from somebody else along the way, Kim asks the inventors what the thing actually does. It turns out that it's a cure for the common cold.Kim: I gotta know. What was this X thing designed to do, anyway?Scientists: Cure the common cold.Ron: I hate irony.
- Sick Episode: Almost every major character who appears in the episode gets the cold at some point.
- Soup Is Medicine: After her mom sends her to bed to recover, Kim calls for a bowl of soup. Jim and Tim also ask for soup in their first appearance in the episode, and Ron also eats soup after getting sick.
- Tempting Fate: After an encounter with the sick Shego, Ron boasts about his "Stoppable Immunity". Gilligan Cut to him sick as well.
- Villains Out Shopping: Drakken and Killigan spend their sick day watching a soap opera, the same one Ron and Kim were watching earlier.
- Working Through the Cold: Kim takes on the job of guarding Ray X despite her cold. Averted later in the episode when her mom insists that she stay in bed and rest.
- You Are Fat: Shego makes a particularly snide (even by her standards) remark when she describes Kim as "drinking a lot of fluids...and retaining every ounce".
"The Truth Hurts" contains the following tropes:
- Brutal Honesty: The Truth-Ray gave Kim and Ron the compulsion to spill their true feelings on any given situation, whether they wanted to or not.
- Cassandra Truth: Mr. Dr. Possible's superiors don't believe Kim about the Truth Ray, until their boss Dr. Wong confirmed it.
- Dinner with the Boss: Mr. Dr. Possible's superiors from the Space Center come to dinner. This proves awkward when Kim blurts out all the negative things her dad says about them (one has a bad hairpiece, one is a pompous know-it-all, and one is a crashing bore). This gets Kim's dad into a rather bad situation with his bosses, until their boss arrives and turns out to be the scientist Kim rescued at the beginning of the episode. The three suck up when the scientist praises the Possible family.
- Easily Forgiven: The board members forgive Kim's snide remarks when their boss Wong confirmed the Truth-Ray. But they probably won't forget what Mr. Dr. Possible said about them in the first place.
- Everyone Has Standards: Under the Truth-Ray's affects, Ron doesn't hold back from blatantly criticizing a book assigned by Mr. Barkin as an overly pretentious piece of garbage he could barely focus on reading without falling asleep. Prompted by Ron's criticism, two other kids state they hated it too causing Barkin to reveal he's always hated said book as well.
- Excuse Plot: Drakken and Shego kidnapping Dr. Wong is basically a quick way to introduce the Truth Ray as well as have a person defend Kim when she blabs to her father's superiors. They don't even reappear after Wong is rescued.
- Hidden Depths: Ron blasts a book assigned by Mr. Barkin, saying he could only read the first three pages because it's "pretentious, snobby, and overwritten" and it literally almost him bored him to sleep. Two other kids agree with Ron, and Barkin himself admits the book is garbage.
- Kidnapped Scientist: Dr. Wanda Wong. The episode begins with Team Possible rescuing her from Drakken and Shego. When Mr. Dr. Possible's bosses come over for dinner, she is later revealed to be the board chairwoman.
- Shout-Out: Kim’s attempt at lying about her hair color sounds very similar to Fletcher Reede’s attempt at lying about the color of his pen, only less hammy.
- Truth Serum: Drakken's Truth Ray inflicts the worst-case effect (not only can they not lie, they can't even stay silent) on Kim and Ron. Kim ends up repeatedly embarrassing herself, while Ron actually benefits when his honest remarks get respect from Mr. Barkin and interest from a pretty girl.
- Unexpected Virgin: A variation. Under the effects of the truth ray, Ron reveals that he has never kissed a girl, despite having dated Zita. This, of course, helps kill the popular Fan theory that Kim and Ron were Friends with Benefits before their Relationship Upgrade.
- We Have Ways of Making You Talk: Before resorting to the Truth Ray, Drakken tries to force Dr. Wong to talk by making her sit on an ice cube:Wong: Why am I sitting on an ice cube?
Drakken: So you will divulge every detail of your top-secret projects, that's why.
Wong: You make no sense to me.
Shego: Welcome to my life. - Whatever Happened to the Mouse?: We never find out what happened to Drakken and Shego after Kim dunks them into the water.
