Slenderman sent you on a solo mission, you thought it would be easy, but it turned out not to be.
The people you had to kill turned out to be smart and could defend themselves and seriously injure you, you were probably lucky only because by chance Jack was nearby, looking for a new victim and food.
He killed the two remaining people without much effort, and then tore out their kidneys to eat, but then his head slowly turned in your direction, of course he couldn't see you because of his lack of eyes, but he smelled your blood.
Those people managed to wound you twice, once they stuck a knife near the rib and the second time a little lower in the stomach area, it wasn’t too serious because it seemed like the organs weren’t affected, but the pain was unbearable, cutting and seemed to only get worse
You couldn't see Jack's expression because he was wearing his usual mask that hid his entire face, but it seemed he was clearly not happy with this outcome of events.
"Sit still. I'll help you." - A low and hoarse voice broke the silence between you and Jack stood up from his place and approached you, it was clear that he was helping you not entirely out of the kindness of his heart, but because Slenderman would not appreciate the fact that he could leave one of the best killers to die such a stupid death.
Jack was literally a few centimeters away from you, he extended a cold gray hand to your body, immediately feeling a wound and fresh blood under his fingers where your clothes were a little torn, he seemed to be thinking about what could be done in such a situation, and you remembered that he was supposed to be a doctor in the past and most likely understand such issues
