Kate is soon found in the Kullman mining shafts chasing Lauren. At this point Kate has become a proxy to Slender Man known as "the Chaser". It is unknown what happened to her, but she now seems feral and wears a mask and has black substance around her eyes and mouth with very pale skin, possibly due to residing in the mines. Her hoodie and hands are also heavily stained in blood; it is unknown whose blood it is. It appears that her eyes are very sensitive to light. She gets dazed when Lauren concentrates her flashlight's beam towards her face. She also appears to snarl and growl. She keeps chasing Lauren until Lauren finally gets on the lift and escapes. In Chapter 5: The Arrival, after Lauren gets knocked out by a proxified Charlie, Lauren wakes up in a room with him, after collecting a book, Charlie disappears, and the crying of Kate is heard, Lauren finds a normal Kate (unmasked and unhooded as well looking badly burned) crying in a corner, Lauren approaches Kate, only for her to turn back into The Chaser and kill Lauren, the last shot of the game shows Lauren's limp body (legs shown only) being dragged away by either Charlie, Slender Man, or Kate.
