Nightmare Fuel / Find Us Alive

• Harley's quiet, terrified monologue during the blackout in Episode 04. It's laden with Nothing Is Scarier, and really hammers in the hopeless situation the site is in as he talks about the terrifying stillness, the "scavengers" shaking everyone down for supplies, and his fear for Lancaster's safety.
  Almost one hundred people in this building and it was still as the grave. For a while, I actually worried I might be the only one left somehow. Like everyone else had cannibalized each other in the violence and everyone was dead, and now it was just... me. Alone, in this pitch black, labyrinthian research facility.
• Dash Three-ified Lancaster in Episode 27 is uncanny enough on his own, but hearing the normally unflappable Harley scream and beg for his life as his closest friend takes a scalpel to his arm is heartwrenchingly terrifying. He's trapped, suffocating, and panicking, and the one person who he should be able to count on to rescue him is ignoring his injuries in favor of carving a dimensional rift into his skin.
