Literally the only point of the MC being a sleepwalker needing to be locked in and her mom dying/losing the apartment/trauma superpak was that one moment where Verity locks them in the room. Jeremy breaks out from the window and comes back around to unlock it from the outside iirc? I forget what but it bought Verity an extra 60 seconds to do…something. Idk it was dumb and convoluted, she could have easily just set up an old house with finicky locks to add to a creepy atmosphere.
