When Aiden finds himself in the Edge, it is a different experience. Not only is he just a passenger, there is a vibration running through him where there has been nothing before. He can feel it building, as though trying to shake him apart. Aiden feels his heartbeat falter and twitch with the force of it and fights not to pass out.
He sees Reacher clinging to his hand. The Guardian is holding the Key out to Aiden, his mouth forming words making no sound. Aiden watches in horror as the crack widens further, light blinding him, tearing through him. She barely has a voice anymore, only a thin wail reaching him through his contact with Reacher. Aiden raises his hand to ward off the brilliance, just wanting it to stop. Instead, his fingers brush the Key.
