The next several days went well. More tests were made and Trip showed everyone what they missed when they were "out," including the technology. Speaking of which, Trip found the programming he had been looking for and reformatted it to accommodate the selected pony. All got special analyzing software, including Trip, but after that, everything varied. Mirage received software that could allow her to see the entire electromagnetic spectrum, so that she could manipulate light beyond the eye. Amplitude and Axle were given retractable blades in their wings. Amplitude also could now use sonar and special sound waves that could obliterate a cinder block wall while being at too extreme of a frequency to be heard. Hazard's systems were restructured to increase agility and acceleration. Frankly, Trip claimed that bells and whistles would simply weigh Hazard down. 

Everyone was adjusting, but Hazard was still trying to let go of what happened. As was a certain mare.

Tesla had done a quick job interview and was now hired as the night watchmare. Night was approaching fast, and she made sure to bring the board. 

At the same time, Trip tapped into the security cameras' wiring. 

"Here comes the watch guard. It's a pity. For the time when I, myself, was out, countless were killed and never found. At least when I was up on my hooves again, I developed a plan: when an animatronic strikes, I teleport the pony out. I can't risk going out there."

Amplitude piped up with her usual questions, "Why not? You've shown us all that you could take them all out with one hoof tied behind your back."

"Remember when I told you that the victims stuffed into the suits would act like Freddy or any of the others if they're activated? Fuse hasn't activated any of them yet, but if she knows about what we're doing, then she surely will."

Everyone was silent. There wasn't much they could do except watch and wait.

Tesla walked into the office and was settling in. It seemed like an easy job for anyone else, but she quickly set up the board and waited. Suddenly, a strange, demonic laugh echoed through the halls. Tesla checked the cameras to see what was going on, and found Freddy in the dining areas. Tesla gasped, suddenly feeling uneasy. She could have sworn that the animatronics had been powered down. And even though they sometimes left the stage to interact with guests, something didn't seem right. She quickly shut the doors and decided to try to talk to Mirage.

Meanwhile, in the lab, Tesla was being watched by a hidden camera. 

"Wait a minute, is that..." Mirage didn't even finish the sentence. She just stood there wide-eyed and open-mouthed. Everyone then recognized the pony as the one that Mirage saved. And Mirage could tell that she wasn't taking things well.

"Hello?" Tesla called to the dark, "Mirage? Are you here? It's me." She was replied with a flash of hallucinations; Bonnie's face with invert-colored eyes and the words that Tesla had spoken: 'It's Me.' What did that mean? Tesla recalled the articles that she saved and remembered something about the animatronics resembling living carcasses. 

'No... It couldn't be...' Tesla started to panic. She checked the time on the tablet, only to see that she had limited power that was half-gone. What sick joke was this? Was her sister angry with her? Had she been stuffed? She cried out in desperation. 

"I'm sorry, Mirage. I'm sorry!" She was living one of her worst fears: the fear of that day.

Mirage watched on, shocked at what she saw. She had never seen her sister act like this before. 

"She's going to die from a heart attack before they get to her," Axle commented, resulting in a glare from Hazard.

Mirage, who had been silent all this time, said, "We have to get her out. I can't let her face my fate. I can't stand to see her like this." She was talking more to herself than anypony else. She didn't care what the others would say; she had to talk to Tesla. She had learned to teleport as another tactic for evasion, and that's the spell that she used. Trip saw the sparks flying from Mirage's horn, and understood. He never revealed the truth about the pizzeria to anyone, but this was Mirage's sister. He let her perform her spell.

At the same time, Tesla had reached her limit. The power ran out and she didn't notice it until she heard an eerily cheerful song playing. She collected herself and looked up to see Freddy staring at her. Then there was a bright violet flash, much like Mirage's aura...
