She enters and the door closes

Katelyn steps into the building. In front of her is a long hallway with doors on each side. The hall is a clinical white with too-bright fluorescent lights almost making it unbearable. The door closes itself behind her and Katelyn jumps as it slams and clicks. She turns back toward it only to find there's no handle or knob on this side. It's simply flat as if it's part of the wall. Katelyn was already anxious about following these instructions but no her heart is thumping loudly in her ears. It's almost as if the silence of the long hallway is amplifying her rising fear. "I guess I'm not going back that way," she whispers to herself.

The red-haired girl starts walking up the hall and checks the doors until she finds 6C. Sure enough, there's a small monitor on the wall. The screen is black with green writing on it, like an old fashioned computer. There is a question on the screen above a keyboard: "Who welcomes you?"
