Heartwarming / Mr. Young

• In the pilot, first thing Childhood Friends Adam and Derby do when they met each other is hug each other. Now Derby is not Adam's best student, but it shows they are good friends who have probably haven't seen each other in years.
  • The first time Adam sees and meets Echo, he can't stop smiling. Also, the fact that the first word he says after meeting her is her own name. Not to mention that Echo is not exactly a popular girl and Adam still fell for her anyway.
• Mr. Ballerina: The joy and relief Slab feels by Adam and Derby joining his ballet class, because it makes him feel that he doesn't have to hide his love for ballet as a boy anymore.
• Mr. Meteor: Adam's attempt at a Dying Declaration of Love to Echo. The fact that as they all think they're about to die, he says: "Only one thing I want to do before it's too late!"
• Mr. Picture Day:
  • All the trouble Echo goes through to give Adam all the school experiences he never had, even though she comes off as slightly psychotic on occasion.
  • There's also his reaction to seeing her prom set up and her dress. As well as thinking the prospect of a horse-drawn carriage ride to be quite nice.
  • When Echo's date breaks up with her, Adam steps in to dance with her.
  • Adam also telling Echo that the best thing about the high school experience is that he gets to spend it with her (backpedals after and quickly says "you...guys" to cover).
• Mr. Moth:
  • Adam and Echo's flirting in the beginning is both funny and Adorkable.
  • Until he becomes desperate, Adam doesn't resort to using the pheromones right away because he wants Echo to be genuinely interested in him and not rely on a chemical to do so.
  • Seeing the two holding hands later on and barely being able to break apart when Echo agrees to go to the party for Dang with Adam later on. You just want to melt inside.
  • Echo laughing at Adam when the moths eat his clothes and reduce him to his underwear could be interpreted as she's laughing because she finds it charming and not necessarily because it's degrading to him.
  • The whole episode is revealed to be Echo's dream. Meaning that she subconsciously knew Adam cared about her like that and had a good idea of his feelings for her, suggesting she may have feelings of her own for him. The look the two exchange at the end of the episode just brings it home.
• Mr. Claus: The episode ends when Adam turns to everyone and says "Merry Christmas everyone!" and they respond back in kind.
  • Call backed at the end of Mr. Elf when Adam uses the taser he used on Derby to turn on his electronic Christmas tree and say it again. Cue all the students letting out an "Aww!"
• In Mr. Space, Adams friends tell him they do respect him as a teacher and he agrees to quit his job at the space program.
• The final interaction between Adam and Cyber!Echo in Mr. Pixel.
  • Fridge Heartwarming: Since Derby designed the Cyberworld, he probably designed Cyber!Echo to have a crush on Adam.
• Mr. Rock Star: Crossed with funny, when Echo says "I'll love you forever!" if Adam can get his rock star friend to come to the school, Adam responds by reciting wedding vows, yelling "I do!" and throwing flower petals up that he's pulled out of his pocket.
  • When he says he can introduce her to the rock star, Echo excitedly hugs Adam while thanking him incessantly.
• Mr. Poet: While everyone else is puzzled by Echo's poem that curb stomps littering, Adam applauds it.
  • Echo kissing Adam on the cheek and him making up the poem inspired by her right on the spot.
  • Everyone else is moved to tears by Adam's poem, while Echo applauds it.
• Mr. Spring Break:
  • Adam and Echo Almost Kiss when the Kiss Cam lands on them.
  • Adam getting Mrs. Byrne to take him and Ivy to the same resort just so he can be close to Echo.
  • Adam doing everything he can to try to find a way in where Echo has been abducted and rescue her.
  • Echo telling Diego that she can't be with him because she's in love with Adam. Also, the fact that it gives Adam even more confidence to go in and rescue her. Echo's Love Confession also prompts Adam to call out "Now unhand the love of my life!" Even though it's revealed that Echo only said what she did to get Diego to back off, Adam still meant every word of what he said.
  • Echo is also genuinely happy to see Adam when he comes to save her. Plus, the fact that of all people to say that she was in love with, she picked him over everyone else.
  • Echo trying to hug Adam while still chained up as well.
• Mr. Invisible:
  • When Echo shows Adam her Lady Guinevere costume for her history project, he mistakes it for a wedding dress and rips off his clothes to reveal a tuxedo. He's prepared to marry her right there and then thinking that's what she wanted.
  • Echo rushed in to show Adam the dress. She was excited for him to see it.
  • Adam trying to sabotage Echo and her partner thinking they're getting romantic is this in hindsight since her partner ended up being a jerk.
  • When Adam enters the room in the invisibility suit, Echo sees the door open and close on its own, but just shrugs and turns away. Her shrug is one of the most adorable things and major props to Matreya for once again displaying how well her mannerisms fit the character.
  • When Echo starts crying after her history partner rejects her romantic advances and Adam (while still in the invisible suit) hands her a handkerchief. The fact that he nearly takes the suit off so he can be there for her also counts.
  • Derby's attempts to comfort Echo after seeing her so upset.
  • Adam pulling the sword out of the stone for Echo, leading to their hug and Almost Kiss.
• Mr. Sci-Fi: After successfully negotiating the safety of Earth with the aliens, Echo asks Adam what she can do to thank him and he tells her that she knows what he wants. He takes her hands in his, they move forward for a kiss...but then the whole episode is revealed to be All Just A Pitch.
• Mr. Tutor: Echo hugs Adam after he says he's getting them tickets to Rock Fest. During which, Adam also smells her hair.
  • Also, Adam realizing that Ivy is actually fairly smart and wondering why they don't talk more. As annoying and superficial as his sister can be, he still wants a relationship with her.
• Mr. Heart:
  • Had she not gotten sick, Echo would have agreed to go out with Adam.
  • Adam's willingness to go all throughout Echo's body in order to cure her cold.
  • Echo shrugging when she decides to use the cotton swab and then shrugging after she comments on the oddness of seeing the wax replica Derby made of himself before throwing the swab away.
  • Echo saying "I love Adam Young" after he touches the neurons in her brain. You get the feeling that Ms. Zizzleswift was also saying what she knows deep down to be true too.
• Mr. Sasquawk: When the planes fly by the skyscraper and the wind knocks Echo off balance, Adam catches her in his arms.
  • In a sad way, Adam having to declare that he has no romantic feelings for Echo to keep Sasquawk from throwing her off the building. Also, Echo believing before that that Adam did actually have feelings for her.
• Mr. Double Date:
  • Echo going to great lengths to try to find Adam the perfect girl.
  • Echo finally realizes that she's developing feelings for Adam and considers setting him up with her.
  • The fact that Adam nearly set Echo up with him (if not for Derby's big mouth) and that finally would have ended the Unresolved Sexual Tension.
  • In a strange way, Derby realizing he's in love with Haley Strauperson.
  • Adam and Echo each tell the other that they hope they find the right one.
  • The fact that after Mr. Sleepover and Mr. Heart gave Adam more of a Stalker with a Crush vibe, this episode, Mr. Love Letter and Mr. First Impression proved his feelings for Echo to be truly genuine and more authentic than they'd ever been before.
• Mr. Love Letter:
  • Slab and Tater are each so moved by the letter that they each carry a copy of it for inspiration.
  • Derby expresses how impressed he is by the letter as well.
  • The love letter itself speaks volumes about how Adam feels about Echo:
  "My Dearest Echo, From the moment I first laid eyes on you, I couldn't imagine a day without you. You are my sunshine and my moonlight. You are not only the most beautiful girl I have ever seen, you are smart, funny and have a passion for life like no one else. I could fill libraries with words about you, but I really only need three. I love you. Yours forever..."^note Adam's name is cut off by the weevils eating it.
  • Also the fact that not only is Echo clearly touched (without knowing he was the one who wrote it), everyone else awws as she reads it.
  • Adam going to the lengths he does to prove that Jared is a manipulative liar, putting himself at risk when Slab gets the hate letter he wrote to try to discredit Jared.
  • Echo wishfully expressing her desire to be with the one who wrote the letter at the end of the episode and holding it with a sigh after Adam suggests holding on to it to think about the guy who cares so much about her (AKA him).
• Mr. Freshman: Young!Adam briefly being in the same 4th grade class as his future students, including Young!Echo, though it turns out they didn't officially meet because he didn't like girls then.
  • In a way, Young!Derby and Young!Slab trying to encourage Young!Adam to pay attention to Young!Echo.
  • Fridge Brilliance: Adam realizing how dumb he was to not try to get close to Echo when they were kids is what probably prompts him to finally have his Love Confession to her in the next episode! Speaking of which...
• Mr. First Impression:
  • Adam telling Derby how he can't imagine living the rest of his life without Echo.
  • Adam finally declares his feelings to Echo, along with an elaborate set up he worked on for her birthday with fireworks and the letters of her name lighting up on fire.
  • By the end of the special, Echo kisses Adam. It turns out she has feelings for Adam and when she seemingly rejected his Declaration Of Love it was because she wasn't prepared.
    • Heartwarming in Hindsight: It also shows that Adam didn't need to change anything to begin with. All he had to do was wait and that waiting (as well as all the waiting he did before) finally paid off.
    • In addition to that, Echo's reactions are also clearly not just that of shock, she's deeply moved too, but just chose not to act in the moment. Her calling back to this in Mr. Kidd clearly reinforces it. Thinking about it from her perspective, the guy that she loves has just told her that he's been in love with her since Day 1. If she'd looked right in that moment, she would have kissed him right there and then. No question about it.
    • However long Echo was gone, she clearly put a lot of time and effort into cleaning herself up to be more presentable for Adam, showing how much he was truly worth it to her.
  • Continued with Mr. Memory as we see Adam get to finally talk freely about his feelings for Echo to her with: "Echo, you're my favorite. You've always been my favorite." There's also them directly saying "I love you" to each other for the first time and how they gush about the fact that they're dating to Derby when he accidentally walks in on them kissing.
    • Even them playfully insulting each other is unbelievably adorable. As well as {Adorkable}.
    • Derby, though he immediately bad mouths Adam to Echo right after, expressing his delight and enthusiasm over the two finally getting together.
  • Seeing Adam and Echo getting romantic on a date together (laughing and holding hands). That is until before Derby kills the moment.
  • It gets better in Mr. Kidd, they kiss again and it was enough for Echo to get her memories back that Mr. Kidd wiped away.
    • Though that's somewhat ruined by the fact that it works on everyone, no matter what their relationship with Adam is.
    • That said, the fact that it was a kiss that undid the damage is still amazing in itself. Plus, we don't see any of the other kisses so it's actually not really ruined in that case.
  • Another in hindsight: Right before the kiss helps Echo remember, she describes that she knows what she and Mr. Kidd have is real and how she knew it was real. Without knowing it, she's describing how she knew what she and Adam have is real and how she knew it was real. If you took exactly what she said and replaced "Mr. Kidd" with "Adam", you'd have the undisputed facts right there of what she truly meant. You look back at the scene she's describing in Mr. First Impression and it's right there plain for all to see.
  • Adam and Echo cuddling at the end of the episode.
• In the episode Mr. Memory, Ivy realizes Slab is the only boy in school who didn't ask her out and get rejected. So she tries to get him to ask her out, at the end of that subplot, Ivy asks Slab why; he admits he does like her but would never ask her out because he knows she would reject him. She says that she wouldn't and finally talks Slab into asking her out. She says yes, and the two kiss.
• Mr. Court: Adam agreeing to go jogging with Echo even though he clearly doesn't enjoy jogging itself. He's only doing it for the girl he loves.
  • Adam ogling Echo while she cheers and doing it openly. While he's called out for it, he's allowed to freely without it being too weird now that she's his girlfriend, depending on production order anyway.
• Mr. Budget: Almost every situation in the episode has Adam siding with Echo on the problems that arise. It's clear the two work together far more closely than they have before now that they're dating, depending on production order anyway.
• Mr. Interview: When asked if being the same age as the girls in his class complicates things, Adam imagines several of his greatest hits with Echo, which are clearly even better now that they're together. Again...depending on production order.
• Mr. Spin-Off: Adam guessing Echo's idea for the show is a romantic comedy about when they're married. Makes the fans really wish it would happen. Despite not being given any footage like the other suggestions in the episode, unlike them, it's left to the viewers' imagination.
  • It's buried, but despite Echo stating in her spin-off (and in Ivy's) that a marriage to Adam would be loveless, the fact that Echo imagines her Romantic False Lead as Adam and that he turns out to be a romantic false lead means that Echo really only sees herself having a future with Adam and no one else and that is further proven with Mr. Finale. Makes the whole thing feel a whole lot less Ass Pulley.
• Mr. Finale:
  • Echo saying the best thing to happen to her was hooking up with Adam. Also goes to prove that she didn't really mean what she said about their relationship in Mr. Spin-Off and that it was all just a throwaway bit.
  • The fact alone that after the Time Skip, Adam and Echo are still dating. Meaning they've been happily together for over a year.
  • Ivy calling Slab a good boyfriend.
  • Mrs. Byrne deciding to settle down with Master Ki.
    • The fight between Ki and Dang, where Ki chases Dang across the world, punching and kicking him all the way. Dang just stands there bored because he can't bring himself to hurt his Master.
  • After getting the feather impaled through his head and surviving, Adam settles for tickling Echo with the feather and making her laugh when it gets in the way of kissing her.
  • Before that, Adam tells Echo that she means far more to him than any scientific discovery he could make.
  • Principle Tater's graduation speech.
    • At said graduation Slab thinking his was going to spend the rest of his life in High School is called up to receive his diploma, he is overjoyed.
    • Heartwarming in Hindsight: In a previous episode, Slab befriended some college jocks and hoped to join them, and now he can.
  • Adam goes up to the podium to be there for Echo after Tater calls her name.
  • Echo comments on being happy to have met and found love when she collects her diploma. She's looking right at Adam when she does so and he's looking right back at her.
  • After the graduation, Tater approaches Adam with a list of his students next year, Adam says he wishes the next science teacher good luck, saying he only became a teacher so he can have the high school experience he never had, and now aspires to be a college professor. Adam points out that Tater never wanted him as a teacher in the first place, Tater says yes and admits that Adam made the place fun for him.
  • At Adam's first day as professor, he see's his first class consists of his old class. He points out they passed science and don't need to take it, and realizes they are here because of him.
  • Even though Slab does it facetiously afterwards, Echo calls Adam "Professor Sweetie", meaning that they've been together all through the summer as well. At that point, it shouldn't be long until they've been together two years.
  • The lesson in the class at the end harkens back to "mold growth" from the first episode. Meaning whether it was a prank or not, Adam getting the sandwich half tossed in his face is actually connected this time and shows that he truly did inspire the students.
