These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Moment of Heartwarming: Many scenes where Elianto appears, expecially when Doctor Satagius or Talete promises to make him heal. Also when all three the groups meet in their way back to Earth and Elianto meeting with his family.
Elianto's dialogue with Ghost Talete.
Nightmare Fuel: The Sadic Angels' boss proposition to Carmilla can count as this, depending on your sensibility.
Squick: Hilariously done with the Triperot clan, whose members never shaves, never cut their hair and never wash. Also when Carmilla make a strip show for the aliens of Bludus, causing a .... mess...
Tear Jerker: Surprisingly has some, including one where Persefone, while making the healing elixir for Elianto, predict what would happen if they fail in an alternate, crapsack future.
