Derpy felt her back leg drag behind her. The weight was painful, but she kept going. The Doctor helped pull her along. She ran out of breath more quickly now. They were closing in on the boutique now. Derpy turned her head to look. The statues had noticed them. ‘How could they not? They just have to follow the sounds of dragging stone.’ She thought, she kept an eye on them, still a bit of a way off, as the doctor stopped.
“Remember, don’t look into their eyes, Derpy.” He warned. He unlocked the door with his sonic, opened it, pulled her through, and locked it behind them. The boutique was dark and silent now. The Doctor said, “Derpy, put a mirror by each window!”
“Doctor, I don’t think I’m the best mare for the job….”
He looked down to see her stone hoof, and remembered how easily she tended to trip in four normal hooves, “....point taken….”. He nodded, pushing a mirror to each window as quickly as he could. “That should buy some time,”. He looked back at her. The entire leg was stone now, and the feather was shrinking as more of its mysterious energy transferred itself into her body. “I take it I have until the feather disappears to figure out what to do?” He thought to himself.
Derpy’s eyes glowed again and she spoke, “Doctor, you are only prolonging the inevitable. You may think us monsters, but trust us, you would be thanking us if you understood.”
“Get out of her mind!” he demanded, firing his sonic screwdriver at Derpy. As before, her eyes returned to their normal color. The spread from the feather seemed to be happening faster though. “Derpy. Sit right in the middle, and conserve your strength. I’ll figure this out, I promise.”
“O...okay.” She stammered. She was glad to rest. She sat slowly, trying to get herself comfortable. She wondered how high the moon was in the sky. When the other ponies woke up, they would see the statues in other places. And they would think it some joke until they were sent to the past, or worse. She looked over to the Doctor, muttering thoughts under his breath. She looked down to her hind leg. She tapped it like the Doctor did. Her heart dropped. “I’m turning into one of them?!” She thought. Desperate to stop it, she tried to pull the stone feather out with her teeth. She grunted as she fought against the sharp pain, fighting harder and harder against it, but it was too much. It felt like she was tearing flesh and muscle to pieces. She screamed and dropped to the ground, crying out from the pain and fear.
“Derpy!” The Doctor ran to her. He couldn’t bear to hear her cry out like that. “It’ll be OK, I’m going to get you out of this!”
“No… it’s not OK. We’re losing.”
“No we’re not, we’re not done yet!”
There was a terrifyingly loud pounding knock at the door.
“I’m scared, Doctor! These things won’t stop chasing me and I don’t know why. To make it worse, your trapped too! Just let them take me. Get away from here safely, and find another companion. Somepony better.”
“You didn’t leave me, remember? Why would I ever leave you?! Besides, I don’t want another--”
The door exploded into a hundred splinters and before either of them could even turn to look, all three angels were inside and had closed the gap. They were ignoring Derpy now, and focused on the Doctor. He now realized that he was crying too, and couldn’t see much of anything through the tears. He scrambled backwards up against the wall, trying to clear the water from his eyes to get a focus on the angels. By the time he did, one was already practically on top of him. Bent over as it was, its forelegs blocked his escape to either left or right, and any attempt to slide would’ve brought him in contact with the hind ones. He was completely trapped with nowhere to go but into the distant past. The other two angels just stood near the door to observe their ultimate victory against their great nemesis.
Derpy’s fear merged with anger at the prospect of what was about to happen. She could mentally picture the Doctor disappearing into the past. She saw herself becoming one of them. What next? Her imagination went wild and suddenly, half of the ponies in all of imaginary Equestria were like them and the other half gone to some distant time. And the Doctor would be alone again...lonely and heartbroken...The look of terror in her eyes was replaced with fury. Adrenaline took over and she barely felt the pain in her leg anymore. “You… leave… him…. alone!!!” She rushed at the angel, screaming.
The Doctor saw from the corner of his eye what was about to happen. “Derpy, don’t!” But it was too late. Derpy leaped from the ground, using her wings to accelerate even faster, and plowed head-first into the stone figure. Everything seemed to freeze for a moment; nothing could be heard except for a deep droning sound. A blinding white light shot appeared from where Derpy’s head connected with the angel, rays of light shining across the showroom. The Doctor fought to keep his eyes open, in spite of not wanting to see the inevitable. But Derpy didn’t disappear. Cracks emerged on the angel, spreading around its quantum-locked exterior in all directions. Time sped up back to normal and the creature exploded into a million fragments. The blast of energy slammed the Doctor against the wall and sent Derpy flying in the opposite direction. Clothing racks and mannequins were knocked over and every mirror and window immediately smashed. The Carousel Boutique shook all the way to its foundation, ringing out an explosive noise that must have been audible from miles away.
The Doctor stirred, quickly grabbing his head which was throbbing fiercely. With his ears still ringing, he looked around. Dust was hanging in the air making it difficult to see, but both of the other angels were gone. “Derpy? Derpy!” He spotted her against the wall at the other end of the room, unconscious in a heap; small bits of rubble covered her motionless body. He ran over as fast as he could and turned her over. “Derpy, are you okay? Say something!” He scanned her with the sonic and saw that she was alive. But her body was exhausted from the overexertion. He checked her stone leg. It was covered in cracks and wasn’t spreading any further. And then it broke apart, falling to the floor like a cast being removed, revealing her normal leg.
Derpy slowly opened her eyes and glanced around the room. “I’m… sorry. I just don’t... know... what went wro--”
The Doctor grabbed her cheeks and looked into her eyes. Tears of happiness were obscuring his vision. “What went wrong? It’s what went right!” He kissed her on the forehead. “Derpy you Mare of Infinite Possibilities! You destroyed a Weeping Angel and the other two ran away in terror! Nobody has ever done that before! You are amazing!”
“I did... another thing... right?” Her lips cracked a slight smile.
The Doctor jumped upon hearing a sound behind him, thinking the angels were back. Rarity stood there at the bottom of the stairs, wearing a nightshirt made of intricate white lace. Her jaw looked like it would hit the floor as she scanned the room. “What in the name of Celestia did you do to my shop?!”
