History TearJerker / TsubasaReservoirChronicle

* During Acid Tokyo when the true nature of [[spoiler: C!Syaoran is revealed]] and Sakura is ''begging'' him not to go after she receives the feather was too much.

** And let's not forget when she [[spoiler: comes back, so hurt that she collapses, and yet the first thing she does it to apologize to Fai because she couldn't help him when he was in pain. Fai wasn't the only one who cracked there.]]

* The moment during the showdown with Ashura, when Fai screams that [[spoiler: he just can't bring himself to kill the first person ever to show him kindness.]]

* Chapter 210, in which [[spoiler: C!Syaoran dies. It isn't until he says "Kurogane-san... Fai-san... Mokona..." that it hits home that this isn't the unstoppable, murderous clone that's dying, but ''the Syaoran we started the series with.'']]
** Also, in the same scene, as [[spoiler: Syaoran is dying: he returns his stolen magic to Fai, who says "It would have been much much better if you had just come home." That's right, this is the boy who betrayed him and [[EyeScream tore out his eye]] ''with his teeth,'']] and Fai is still willing to forgive him and just wanted them to be a family again.
* The twins [[spoiler: Fai and Yui]] have been condemned to be imprisoned for eternity without even each other for comfort. However, they are given an escape clause: one of them can die and free his twin of his misery. In response, Yui and Fai look into each others eyes, and without saying a word they clasp hands. It's the last moment they ever have with each other, until they lock eyes the moment before.

* [[spoiler: Also the callback to Kurogane's backstory in Celes. Tomoyo closes his mother's eyes and tells him to let her rest, and that's basically exactly the same thing Kurogane tells Fai to do for his twin.]]

* Remember this? At the time it was a really cute thing for Fai to say, until you later see his backstory and [[spoiler: how he learned to [[StepfordSmiler Stepford Smile like a champion]] from Ashura. Then it wasn't so cute anymore.]]

* In Nihon when [[spoiler: Clone Sakura is stabbed, by Clone Syaoran of all people, and dies in his arms. She wasn't even able to say 'I love you' before she died. And Clone Syaoran's cries just make you want to cry.]]

** Oh and that showdown in general. [[spoiler: Fai's ''face'' when he thinks Ashura just killed Kurogane.]]
* Chapter 210, in which [[spoiler: C!Syaoran dies. It wasn't until he said "Kurogane-san... Fai-san... Mokona..." that it hit home that this wasn't the unstoppable, murderous clone that was dying, but ''the Syaoran we started the series with.'']] Needless to say, the tears came fast.

* Kurogane's backstory. Just... all of it.

* [[spoiler: Also the callback to Kurogane's backstory in Celes. Tomoyo closes his mother's eyes and tells him to let her rest, and that's basically exactly the same thing Kurogane tells Fai to do for his twin. Instant heartbreak.]]
* Oh, and for this one only two words are needed: "Don't disappear!"

** For this Troper that comment came with a side dish of FridgeHorror: "...like food to a starving man..." showcases the sheer desperation and pain of Syaoran because Fai, [[DarkAndTroubledPast of all people]], knows very well what it feels like to starve (remember the state he was in when FWR talked to them?), so the comparison is not made lightly.
* Let's not forget in Nihon when [[spoiler: Clone Sakura is stabbed, by Clone Syaoran of all people, and dies in his arms. She wasn't even able to say 'I love you' before she died. And Clone Syaoran's cries just make you want to cry.]]

** And later, when she goes out to [[CrowningMomentOfAwesome kick mutant butt]] and is [[BreakTheCutie beaten bloody]] in the process.

* Just the general situation for Syaoran. Every time Sakura regains a memory of her past, but he isn't in any of them, even though he remembers everything that happened perfectly, you can just see his heart getting ripped out. Added onto that, Sakura's desperate desire to remember that "someone" who she can't possibly recall no matter what, even though she knows that person was so important to her. Even before CerberusSyndrome set in, this series was heaps of heart-breaking.
