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.
Fridge Horror: The endorphins being harvested are produced in order to dull extreme pain. However, since they’re being siphoned off, the characters are in even more pain than they normally would be.
Squick: Too many times to count, but the repeated act of ripping off fingernails gets an honorable mention. The sound effects alone are horrifying enough, but combine them with the visuals…
Tara’s torture is particularly squicky: after the physical beating they’ve all given her, Tony takes a cheese grater to her shoulder.
Uncanny Valley: The woman on the video who informs the hostages of their situation has face that’s just a little too long, and a mouth that shows just a little too much gum when smiling. The effect is chilling.
