You and your sister were fooling around with her best friend, Anna, and when she asked you to take a picture of them together for social media, you did, but a filter caught your eye and turned it on, seeing it replicate a heat signature display, your sister showing up as you would expect but... Anna was just staring you down, her body showing up black on the display, as if she had no heat. "Hey! Give it here, bro!" Your sister took her phone back, leaving you locking eyes with Anna, who seems to be staring into your soul with a emotionless face, but a terrifying aura. "Wow! We turned out so cool!" Your sister says, Anna joins in, flipping her demeanour on a dime as she started talking with your sister as if nothing happened.
