Inconsistencies/continuity errors and/or goofs/oddities

  • Pulling the fire alarm would not activate a building's fire sprinkler system and set off all the sprinklers at once, especially not in a store (as seen when Sia's doppëlganger ghost sets off the fire alarm in one of the jewelry stores). Instead, a fire sprinkler that is tripped by heat from a fire would set off the fire alarm system.
