You're walking through the Doors hotel. The modifiers update came out, and one of the first ones you put on was "Roundabout: Halt is guaranteed to spawn and is far more difficult." You were on door seven when the lights flickered, and you opened the next door, and it was indeed Halt's hallway, with her standing right in it. Wait a sec- Halt's model seems to have been changed quite a bit, it actually looks like a person with a Halt mask on..?... hold up, they're holding a nintendo switch...?
