Tear Jerker / Tower of Animus

We're not called the Tower of Sadimus for nothing, you know.

• "Forest" (Majora's Mask Link) finds out how "Sea" (Wind Waker Link) got his nickname. He speaks to Fado and finds out that his home was flooded.
• MM!Link and WW!Link meet for the first time. MM thinks he failed as a hero and doesn't deserve the praise WW is giving him.
• An overwhelming majority of the post-surgery threads in the Infighting event.
  • Luke's first surgery.
  • Russia's first surgery.
  • Aragorn's first surgery.
  • Strega!Minato's first surgery.
  • AU!Chidori's first surgery.
  • AU!Jin's first surgery.
  • Strega!Ken's first surgery. A taste of what Strega's lives were like, and Jason even takes Ken's humble request to take the experiments for the rest of Strega into account.
    • All of Strega's are, of course, made all the worse when you consider their pasts.
  • AU!Mami's first surgery.
  • Sayaka's first surgery.
  • William's first surgery.
  • Yu's first surgery.
  • Gamzee's first surgery.
  • Dave's first surgery.
  • Kanji's first surgery.
  • AU!Hei's first surgery.
  • Romeo's first surgery. Except it wasn't really his first...
  • Feferi's first surgery. Like lusus, like daughter.
  • Lucifer's first surgery.
  • The Condescension's first surgery. Not so high and mighty after all.
  • England's first surgery.
  • The Grand Highblood's first surgery.
• Jade!Eridan and teal!Feferi's reunion after the events of Red Dead Virgo.
• And another reunion between Izanami and Izanagi.
• Aaand the reunion between Saki Konishi and Yosuke Hanamura
• A lot of the dream threads probably qualify.
  • Master Xehanort masquerading as AU!Ryoji's Minato in this thread made Ryoji's mun cry. Repeatedly.
  • OU!OoT Zelda's dreams got pretty damn sad, but this one (shared with AU!OoT FemLink) is especially notable since said version of her Link has no idea that at the end of the game all this happens and she would be sent home, leaving Zelda's timeline to be flooded later as per Wind Waker's plot. She never returns because Zelda sends her home, seven years back—thus leading to Hyrule's near destruction by Ganondorf, and the Goddesses flooding it. Ouch! It's shaping up to be a real tear-jerker.
• This meme mixed in with a liberal dose of nightmare fuel.
• Lancer and Lancer's thread during the Tower is Forever Event.
• It's not enough just to lose the most humane tower administrator, but what does he say as he goes out? "I regret I was not able to help all of you."
• Feferi Peixes survived every single event since Infighting. She was in the Something Unexpected crew that went down the elevators, and she kept on going. Finding out that she couldn't trust her friends anymore because of the Rebellion event? Her breakdown is a real tearjerker.
• Riku's reaction to Xion's death during the barricade log during the Idealism event literally made Xion's player cry
