A YouTube web series based on the Slender Man Mythos, it follows three girls; Ellie, Avery, and Macy, who find themselves haunted and hunted after an experience involving a camera. In the ensuing episodes, dosed with heavy Paranoia Fuel, their friendships and sanity become more and more frayed, as it becomes clear that there is no real "escape". Even for the viewer, nothing is quite as it seems....It can be found here.
This series provides examples of:
Adult Fear: The girls are more concerned about / motivated by the wellbeing of their loved ones than their own or ours, be it because of Tall, Dark and Faceless or the Masked Maniac(s?).
Alien Geometries: The girls flee from the Slender Man to a car and end up in an abandoned building and then next to a train in Two. There are several more instances throughout the series, most notably in episode 27.
And Your Little Dog Too: Implied to be the next step of the Antibody Squad after their failed attack on Bowie in Thirty. Avery says they will now go to his house, with the implication that they will attack and kill his family.
Informed Attribute: Macy states that Ellie constantly wears dark clothing and is surprised at the variety of color in her wardrobe when the girls all stay at Ellie's house. However, Ellie is most often shown wearing earthy tones and bright red glasses. In actuality, it is Avery who usually wears the darkest tones of the group.
Jump Cut: It's hard to tell whether it's edited in or if it's just His effect on the tapes, but either way this series is notorious for a copious amount of them.
Unreliable Narrator: In a Slenderseries this is more or less expected. But Subverted. They told the story to the best of their knowledge. The why is the true reveal... which comes at the exact point in the story where they figure it out.
