Quite a lot happened to Terezi in Game Over (the one where aranea jacks up the plans), huh? can you summarize it?

Terezi is being held by Gamzee and Karkat runs past Kanaya to attack him. Gamzee stabs Karkat in the chest with Terezi’s dragon cane and he falls into the lava. Terezi sobs as he dies. Kanaya slices Gamzee in half. Soon afterwards the Condesce unleashes a psionic blast aimed at Aranea but she doges it. The blast hits the stone slab Kanaya and Terezi are on. Kanaya is incinerated and Terezi is knocked away. Terezi then goes after Aranea with her dragon cane and Aranea uses her telekinesis to control Terezi into stabbing herself. She’s then thrown to the ground. Terezi eventually gets up and pulls her sword out her chest.
