I feel your pain Jimmy...
As a Moments subpage, all spoilers are unmarked as per policy. You Have Been Warned.
- The scene in "Brobot" where Jimmy tries to deactivate Brobot. When he explains to Brobot what he's doing, Brobot (who, for once, doesn't sound happy or excited at all) says, "But...but then we can't play anymore. And you're my...big brother." Jimmy starts feeling guilty, and sheds a single tear...which lands in Brobot's circuitry and seems to short him out, causing Jimmy to feel even more guilty. It turns out that Brobot's indestructible, and all the tear did was tickle him, but still.
- "Normal Boy" has Jimmy feeling insecure and sorry for himself after everybody shuns him for being super smart.
- The above Break the Cutie line highlights a general one for Jimmy; even his friends are willing to turn on him if it suits them and the only person he can truly count on is Goddard, who's a robot he built so he probably struggles sometimes with the idea that Goddard only likes him because he's programmed that way...and then decides to live with it because it's better than being completely alone.
- It's painful when you see the build up: His first invention wrecks his house which leads to Judy uncharacteristically asking why he couldn't he be normal and much afterwards, ruining Libby's project by showing his own which left Ms. Fowl and the principle awestruck. Bare in mind Jimmy is just a kid and everyone, even his mother, are giving him a hard time for basically just being super smart.
- During "Return of the Nanobots," Hugh ends up believing he's the last person on Earth due to everyone else being deleted by the nanobots. When he realizes that he's alone, Hugh laments the loss of Jimmy and his wife (whom he actually calls by her first name, Judy). What helps is the absolutely perfect way Mark DeCarlo delivers this line
.Hugh: Without Judy and Jimbo *sniffle* there's no reason for me to live! NO REASON AT ALL! *Hugh breaks down sobbing* - In the Valentine's Day episode where Jimmy kicks Cindy out of his lab and calls her disgusting. You can see that Cindy is truly hurt, thinking Jimmy was playing a cruel joke on her all along.
- "Best in Show" where Goddard leaves Jimmy after everyone (thanks to Cindy) begins to snark about how he isn't "a real dog", complete with Principal Willoughby being outside the Neutron residence and shouting "NOT A REAL DOG!" (even if that was supposed to be a joke how Goddard wasn't just hearing his voice echoing in his head).
- In "Sheen's Brain", Sheen brutally strikes Jimmy and Carl with a lighting bolt after they tell him to put on the helmet one last time. When he sees Carl and Jimmy and believes them to be dead, he realizes he's hurt his two best friends. Realizing what a monster he's become, he voluntarily decides to give up god powers and go back to his normal self.
- Sheen's last words just before returning to normal are "Goodbye brain, old friend." In "Normal Boy," Sheen almost offhandedly mentioned that he sabotaged his highly scientific mind with cartoons and sugar because he didn't want the burden of being a genius. There are some very sad implications there.
- While the scene is funny, the tutoring session offers sad insight into Sheen's mind, he actually does just fine at first, but gets distracted very quickly. There's implications Sheen may have an undiagnosed learning disability like ADHD.
- "The N-Men" is a heartbreaking episode for anyone who truly feels bad for what Jimmy has to go through in his life.
- Just as Hulk Jimmy is about to kill Cindy, she gets down on her knees and tearfully apologizes to Jimmy for hurting his feelings, while admitting that she was wrong to treat him badly. Then, she collapses with Jimmy picking her up and asking, "Cindy what? Like? Loathe? Love?" and then setting her down on the ground as he begins to calm down and realize that Cindy's not so bad after all.
- Before Jimmy turns into a monster, he gets furious and wonders why he's helping his so-called "friends" when all they have done to him was bully and mock him. The way he says it is just plain heartbreaking. You can see that years of insults and hiding his feelings have finally taken a toll on him. Judging by his rant, you can tell Jimmy is trying not to cry.
- The scene where the N-Men get kidnapped by the authorities and they begin to feel guilty about how badly they treated Jimmy. Just before that, Jimmy surrendered himself as well, only for the army and his so-called “friends” to laugh at him too.
- The parents try desperately to get their kids set free from the army, but the citizens keep refusing.
- Several scenes in "Stranded".
- When Jimmy and Cindy are drifting at sea away from their friends.
- Carl, Sheen and Libby try to look for Jimmy and Cindy, but they give up when they believe their friends have drowned.
- At the end, Cindy begs Jimmy to stay on the island with her so they can be together forever, but sadly they can't.
- "The Science Affair"
- Jimmy gets unfairly banned from the science fair because he's rendered winning it pointless. Both sides of the story are pretty sad as well; the kids feel inferior to Jimmy and Jimmy feels bad that he can't show people his hard work.
- Later, Cindy feels bad about getting Jimmy banned, but of course, denies anything.
- You will feel bad for both Jimmy and Cindy at the end; Jimmy lost the Nobel Prize for something that wasn't his fault and Cindy lost the science fair trophy, even though she helped save the day. YMMV for Cindy as she was okay with letting 3 innocent people get killed just to make Jimmy look bad and Libby got through to he by telling her she won't win unless Willoughby gets saved.
- "Billion Dollar Boy"
- Eustace sadistically mocks Jimmy into betting Goddard in a robot battle. Then, when Eustace's robot starts beating Goddard senseless, Jimmy's friends realize that Eustace was just using them to emotionally crush Jimmy. To add salt to the wound, Eustace does a major Kick the Dog moment and throws Cindy down on the ground and reveals his true colors to her. Then, when Goddard is knocked out, Jimmy is heartbroken, thinking that Eustace's robot has killed Goddard and looks like he's about to cry at any moment.
- Eustace's father reveals that his son is a rotten tyrant and he's too wimpy to put his foot down. Luckily for him, Hugh quickly becomes his friend and helps him learn how to properly discipline Eustace.
- In "Make Room for Daddy-O", Jimmy looks at all the photos of the fun times he and Hugh had together and misses having him around.
- Several scenes in "Win, Lose and Kaboom" will tug on your heartstrings.
- Hugh tries to spend some father-son time with Jimmy by helping his son answer the rock's riddle, but Jimmy condescendingly brushes him off and Hugh sadly walks away. Later, when he arrives on the show, he still thinks Jimmy doesn't want him to help. This is when Jimmy truly realizes how much of a jerk he's been to his friends and Hugh.
- Jimmy and Cindy try to vote each other off, for the sake of the planet. Later when Cindy tries to make amends, he brushes her off, unwilling to forgive her. You can see how reluctant everyone was to betray each other.
- When the kids have to jump off the abyss, Jimmy still refuses to be a team player, even though it's their best chance of waking up.
- Earth is saved, but the other team's have to watch their planets explode. You can see that April has tears in her eyes when she thinks Jimmy broke his promise. Luckily, Jimmy convinced his friends to go back and do the right thing.
- "Clash of the Cousins" reveals that Jimmy is the black sheep of the Neutron family because of how different he is. Granted, Jimmy does cause trouble, but some of the things Aunt Amanda says are downright uncalled for.Aunt Amanda: Because of you, the Neutron name isn't respectable anymore!
- Later:
Aunt Amanda: And take that horrible dog with you! - Fans weren't too pleased with the ending of "The Incredible Shrinking Town" which has Cindy having Jimmy's well deserved trophy sawed off after reminding everyone that the town shrinking was his fault to begin with. There's also all the grief Jimmy was getting for his short stature and for something that for once wasn't his fault.
- The fact that Sheen is probably stuck on Zeenu forever with no way to get home is just heartbreaking. Not to mention his grandmother and father must be going insane with him gone.
- Plus, his friends haven't tried looking for him either. That is if they know where the rocket landed. For all they know, Sheen could be dead. No Ending? More like Downer Ending.
- "The League Of Villains"
- While it is played for laughs, the part where Nick breaks his leg again is actually really sad. He starts crying and wonders why it keeps happening to him. It's also implied that he now considers himself a loser.
- When Jimmy is abducted by the villains, Hugh and Judy understandably faint upon seeing their son getting captured.
- When the town is sent back in time, Judy starts crying when she realizes Jimmy is still captured and they’ll probably never see him again.
- Tee becomes a major Jerkass Woobie in this episode when the other villains start disrespecting him for no apparent reason. Sheen and Tee’s bonding (which leads to Tee’s Heel–Face Turn) really gives us some character development for him.
- "The Retroville 9". Jimmy and his baseball team are finally ready to play like a team, until Surprisingly Realistic Outcome happens...
- You will feel bad for Carl in "Holly Jolly Jimmy" when Jimmy crushes his hopes and dreams by saying Santa doesn't exist.
- "Jimmy Goes to College" when Jimmy lies to his parents by telling them he's having good time at college, when he's really miserable and misses his friends (the other students, who are geniuses like him, treat him worse than the students back home). What's more heartbreaking is that his parents pretend not to miss him, which breaks Jimmy's heart more.
- The ending to "Who's Your Mommy?" where Carl has to say a tearful goodbye to Shmengo, his adoptive son.Jimmy: Carl, that hug contained 10,000 volts of pure energy! Wasn't it painful?
Carl: Saying goodbye to your kids is always painful, Jimmy. - In "The Junkman" when Jimmy feels bad for not believing Brobot about the Junkman.
- In "Who Framed Jimmy Neutron?" when Jimmy gets arrested for a crime he didn't commit and his mother starts crying.
- Simply the fact that Sheen's mother is dead can come off as this.
- In "Fundemonium", where the Neutrons are devastated that they have to move and leave all their friends.
- "El Magnifico" focuses on Mr. Estevez feeling depressed because he thinks Sheen loves Ultra Lord more than him and wants to compete with him.
- In the unmade episode "Three's a Crowd", Cindy finally opens up to why she resents Betty, but we also learn that it's not just because Jimmy likes her. She also feels that she will never be as great and beautiful as Betty. Then, there comes Betty's true feelings about herself...
