History TearJerker / StarVsTheForcesOfEvil

* Star gets a HeroicBSOD moment when [[spoiler: Marco notices something about Mewni's history, particularly that of the Monster Massacre when the first pioneers of Mewni arrived at the Forest. She starts off excited about her history, but upon rethinking it and seeing the massacre from a new point of view, it becomes clear that it wasn't a great and mighty battle for independence: Her ancestors stormed a forest and slaughtered countless monsters whose only crime was ''defending their home''. Star, realizing this, is suitably horrified of seeing the battle in a new light.]]

* Star's TranquilFury after Marco admits he underestimated her. It's played for laughs but it's clear hearing that really hurt her.

* Marco's parents [[spoiler: suffering a DisneyDeath]], when Marco assumes they were [[spoiler: eaten by the hydra]]. After he, Star and King Butterfly kill the monster, he runs inside slashed belly calling for them desperately, and even King Butterfly looks worried. Lots of AdultFear in losing your parents on a wild vacation where EverythingIsTryingToKillYou.

* Stars reaction to Marco being captured (she helplessly screams his name while sliding down the vent due to his disguise preventing him from fitting in the vent).

** Star is a genuinely nice girl who earnestly tries to help others... but her unfortunate lack of control over her powers results in her kingdom being endangered, and she's forced to leave her home. She doesn't fair much better on earth either; despite her best efforts, she endangers others and makes things horrible for Marco, much to her dismay.

** Marco, meanwhile, is a safety-obsessed guy who is forced to suddenly live with a dangerous alien (whether she likes it or not) who bring chaos in the form of laser puppies, a destroyed room, literal rain, and cacti. By the end of it, [[SanitySlippage he's going insane]]. Star sums it up well:

** At the beginning of the episode Star asks Marco to put his hand into one of sandwich monster holes, he looks at his arm, gets a quick flash of [[spoiler: Monster Arm]] and nervously refuses. It might mean he is still traumatized by that event and it might create a rift between him and Star somewhere down the line.

** Just to make things worse after she realizes her mistake goes up to Marco's room to apologize to him, only to find out the monsters kidnapped Marco. After Star leaves to go rescue him she tells Mr. and Mrs. Diaz that they're wrong, that this all is her fault. Star already felt guilty as it is for saying that earlier that day to Marco, and now the last thing she ever said to him before he gets taken away is "Sometimes I don't even know why we're friends." And the reason the monsters kidnap Marco is because they want her wand. The poor girl's guilt just doubled and truly feels this is all her fault.

* Star and Marco's fight at the start of the episode. Gets sadder with Star asking why are they even friends.

* Star [[DespairEventHorizon breaking down crying]] when it looks like her attempt to break Pony Head out of St. Olga's has ended in utter failure: Marco's been captured and about to be brainwashed while she had no knowledge of where he is while hearing him screaming in pain, she's stuck in the laundry room, and Pony Head is still hopelessly brainwashed.

** The spirit of the unicorn whispers something to Star just before it leaves. Star begins to have tears fall from her eyes, and never looks away from Toffee as she hears what the unicorn had to say.

* [[spoiler:The moment when Star is forced by Toffee to destroy her wand with the "Whispering Spell" to save Marco.]]

* [[LaserGuidedKarma As much as he deserved it]] for his BadBoss tendencies, it's kinda sad to see Ludo [[spoiler: get betrayed by his minions and thrown out of his own castle by Toffee.]]

* Ludo is genuinely upset at having to fire Buff Frog.

* Buff Frog being thrown out of the only home he'd even known because Toffee knew he was rightly suspicious of him.

** Or that she actually intends to use something that terrible on children in the first place. [[FridgeHorror What made her so...]] ''broken''?

* There's something terribly pitiable about Miss Heinous exposing herself to the school's brainwashing machine; a grown woman so desperate to be perfect that she's willing to use a device meant to be used for children.

* Star [[DespairEventHorizon breaking down crying]] when it looks like her attempt to break Pony Head out of St. Olga's has ended in utter failure: Marco's been captured and about to be brainwashed while she had no knowledge of where he is while hearing him screaming in pain, she's stuck in the laundry room, and Pony Head is still hopelessly brainwashed.

* Possibly worse is Father Time's memories. All he ever did for his entire life was run on The Wheel of Progress, with no way to get off of it and no way to see the world around him. Can you blame him for not wanting to go back?

* The music box tune that plays.

* Marco [[spoiler:watching memories of him seeing Jackie in the exact same way since they were little, realizing he made very little progress in greeting her directly.]] Hits home for people who have been in Marco's position.
