YMMV: Chaos Theory
Fate/Stay Night Fanfic
- Catharsis Factor: Andy Moczo detests Shinji Matou (a sentiment many fans of FSN share), so any time he appears his efforts to do anything productive will end in him being a Butt Monkey - but because he does go too far each and every time, his subsequent clobbering is complete Laser-Guided Karma and he avoids being an Ineffectual Sympathetic Villain.
- Complete Monster: Zouken Matou, as per canon. Here, though, we witness his assimilation of another person's essence without the slightest trace of remorse. To top that off, Saber and Shirou are both highly unsettled by him, while Kirei has an internal monologue reflecting how much the ancient parasite disgusts him. Even True Assassin - while not actually put off by him - notes the hypocrisy and selfish refusal to admit fault in Zouken when the old bastard complains about his situation.
- Les Yay: Caster Alter and Sakura's... mana transfer ritual.
- Nightmare Fuel: Chapter 15 contains a scene where we see Matou Zouken assimilate an innocent's essence as he performs a Grand Theft Me upon her body. Reading it is both horrifically creepy and heartbreaking.
- Shipper on Deck: Irisviel really, really wants Shirou to take care of Ilya. Make of this what you will.
- Tear Jerker: In Chapter 14, Shirou is visited by the disembodied spirit of Irisviel, who softly asks him to do his best to save Ilya.
- Berserker's death in Chapter 22, particularly his regret that he can't protect Ilya any longer, and as he passes she - despite being unconscious - seems to feel it, and starts to cry in her sleep.
- The Scrappy: Caster Alter to some, who believe she has overstayed her welcome and survived situations she should not have.
- The Woobie: Both Ilya and Sakura. The former seems to be becoming an Iron Woobie here, as well.
