* CrossesTheLineTwice:
** Snape using Avada Kedavra on Harry and Ron to get them to stop bothering him.
** Neville's [[spoiler:death]]. Harry, Ron, and Hermione bully Neville to the point where Neville [[spoiler:self-destructs]]. Not funny. But then they [[spoiler:''begin eating his remains'']], and it's ''hilarious.''
** Puppet Draco's [[spoiler:death]] too. Draco getting [[spoiler:decapitated and set on fire by Harry]] is a little too mean-spirited, but Draco [[spoiler:getting decapitated and set on fire by Harry]] ''while Harry sings a happy song about what Draco likes''? Hilarious.
** Some of the entries in "Snape's Diary" are really quite sad. But the dry, [[TheComicallySerious deadly serious]] delivery of lines like this make it impossible to watch with a straight face. (The organ playing in the background and the fact that Snape is lit by a single candle doesn't help.)
--->''Today, I ate some oatmeal for my breakfast. It was flavorless and watery. I thought of my mother. I cried.''
* EnsembleDarkhorse: [[MemeticMutation "I am Snape, the potions master."]]
* HarsherInHindsight:
** In "Trouble At Hogwarts", Voldemort hits Snape with Avada Kedavra during his attack on Hogwarts. In ''Literature/HarryPotterAndTheDeathlyHallows'', [[spoiler:Voldemort actually does kill Snape during his attack on Hogwarts, albeit not in the same manner.]]
** [[https://www.youtube.com/watch?v=ZLmxNaSnTNE "Stopper On My Pain"]], a song about Snape's "lost love". The song, written long before ''[[Literature/HarryPotterAndTheDeathlyHallows Deathly Hallows]]'', was actually supposed to be a melodramatic ballad about Gilderoy Lockhart. Through pure coincidence, it almost perfectly describes Snape's feelings for [[spoiler: his ''real'' lost love, Lily]].
* SugarWiki/HeartwarmingMoments:
** The ending of "Trouble at Hogwarts".
--->'''Harry:''' ''(genuinely relieved)'' Snape! You're alive!\\
'''Snape:''' [[DeadpanSnarker Well, so it might seem.]]\\
'''Ron:''' We love you Snape!\\
''(Group hug ensues, despite Snape's protests, only for Snape to give in)''\\
'''Snape:''' What the--hey, quit that! Oh, you kids. [[JerkWithAHeartOfGold I love you, too.]] Now please get off of me.\\
'''Ron:''' No!\\
''(Snape sighs dejectedly. Dumbledore comes along)''\\
'''Dumbledore:''' Alas! A cornucopia of love! ''(he hugs them, too)'' Awwww.
** Ron offering to have Harry come over for Christmas in "Ron's Parents," recognizing that Harry's unusually assholeish behavior in that episode is due to not having a family.
--->'''Ron:''' Do you want to spend Christmas at my house, Harry?\\
'''Harry:''' ''(immediately)'' Yes.
** The ending of the "Yule Ball" live special, when Harry [[spoiler:talks Voldemort into being nice.]]
--->'''Harry:''' [[spoiler:If it weren't for my friends, I think I would have burned down the school too.]]
* JerkassWoobie: Harry, to an extent. While he ''is'' a selfish jerk, his insistence about not having any tears over his deceased parents in "Ron's Parents" is a bit pathetically sad.
** Even though he grew up to be quite the SpoiledBrat, Harry still had a [[http://youtu.be/NV17_xiA6kM?t=2m58s genuinely awful]] early childhood with the Dursleys.
* MemeticMutation:
** "Snape, Snape, Severus Snape..." "DUMBLEDORE!"
** As mentioned in the Funny section, Ron's "... Why must you hurt me in this way, Harry?" has became a popular reaction image.
* {{Moe}}: Ron gets this reaction from a large chunk of the fanbase.
* NightmareRetardant: Deliberately so when regarding some of the darker aspects of the Wizarding World. How do you make one of the most horrible curses in existence, which has killed many, many people throughout the course of the series, funny? [[https://www.youtube.com/watch?v=-u-H8Dd3g_o Make it the subject of a jaunty toe-tapping musical number sung by Voldemort himself.]]
* TearJerker:
** [[https://www.youtube.com/watch?v=ZEwJkB7K9Og Albus Dumbledore Lists Your Good Qualities]]. Also counts as a TakeThatAudience.
** Some of the entries in "Snape's Diary" are actually rather heartwrenching.
** Neville guilt-tripping Harry, Ron and Hermione into playing "walk in circles" by bringing up the subject of [[AndIMustScream what happened to his parents]].
*** At the end of the episode, Neville self-destructs and Harry along with Ron and Hermione are all [[MyGodWhatHaveIDone struck with guilt over what they said to him]], at least until [[MoodWhiplash they taste his remains and start eating them.]]
** The song "Stopper on my Pain" from the scrapped "Potter Puppet Pals Adventure" movie is a HarsherInHindsight example, seeing as it [[spoiler:fits nearly word for word with Snape's feelings towards Lily, without even having intended to]].
* ValuesDissonance: "Get the Snitch" from ''Potter Puppet Pals Adventure'' contains a non-sequitur in which Ron exclaims, "Sometimes I wish I were a witch!" Modern-day viewers might feel uncomfortable with the song framing this as a laughably embarrassing moment for Ron, especially after [[Creator/JKRowling his original creator]] became known as one of the biggest transphobes ever to write children's literature.
* {{Wangst}}: Wizard Angst!
** So is Snape, Orange One. So is Snape.
* TheWoobie: Snape. Especially in "Snape's Diary".
** Harry gets a moment in "Ron's Parents."
