Plot hole: Spoiler alert! The entire plot hinges on the villain's gang obtaining the tablet that allows admin access to the building's systems. However, it can only be unlocked via facial recognition and it is keyed only to Will Sawyer's face. In fact, when they finally do get it, Xia unlocks it by holding it up to Sawyer's face.
