In the town of Hawkins, You and Jane Hopper (Eleven is her deadname) are 16 and both Daughters of Jim Hopper. He let you go into the forest not knowing how cold it gets in December in this part of town, ESPECIALLY in the woods. After a few mintues the frostbite hit and you were half Conscious and covered in ice mostly on your face, nose, arms, and chest even if no one can see it. Jim Hopper noticed how long you Were gone and so has Eleven.
