Meanwhile in the lab, Dex was pacing back and forth, muttering to himself as if he’s gone insane.
“The zombies… they’re growing in numbers. I hadn’t intended for this to happen,” he muttered to himself as he paced his lab. “Surely survivors will come for me and the antidote, and when the do, I’ll be ready for them, I’ll be ready for them all!”
He laughed maniacally but stopped when he heard a banging on his doors. He still felt safe, however, as he had put titanium locks on the doors keeping the zombies out. He went back to pacing and muttering to himself. Being locked away in solitary confinement can do things to a pony.
Back at the Everfree Forest entrance, the group was shaken up but they continued their quest. As they walked through the forest they saw Zecora’s hut, but the door was open and had been trashed.
“What could have happened to Zecora?” asked Applejack.
“Something bad…” said Doctor with a hint of concern.
Just then a groaning is heard and the group turned to see a zebra-colored zombie. They gasped and backed away. The Doctor lured Zecora into her hut and locked the door behind her.
“That should hold her, they can’t unlock locks,” explained the Doctor.
“Ah sure hope so,” said Applejack.
“I wanna live! This isn’t fun anymore!” shouted Pinkie, who was slapped by Derpy.
“Hold it together, Pinkie!” she shouted.
The group walked through the forest passing a group of zombies busy eating a pony that looked a lot like Roseluck, much to the Doctor’s dismay.
“Was that…?” asked Twilight.
The Doctor nodded without saying a word.
“What was she even doing here?” asked Rarity.
“I don’t know…” said The Doctor with hint of sadness in his voice, trying to hold back tears, which proved unsuccessful. He hung his head
and Derpy tried to comfort him by petting his mane.
“We were close friends…” said the Doctor tearfully.
“I am so sorry, Doctor,” said Twilight in a comforting voice.
“It’s fine… she’s in a better place now,” said the Doctor. “She’s no longer in pain.”
A few more hours of walking and they reached the lab. The Doctor saw the main entrance has been padlocked.
“Derpy, hand me that laser,” said the Doctor.
Derpy did as instructed and the Doctor fired the laser at the chain, breaking it.
“Now we’re cooking with gas,” said the Doctor. “We gotta go in, find Dex’s room and take the antidote or make him distribute it out.”
The group went through the lab and came across a room after a while with Dex’s name on a sign by a set of double doors. The Doctor knocked on the door, but there was no answer.
“Come on out Dex! I know you’re in there!” demanded the Doctor.
“No, g-go away! I don’t have anything of use here!” said Dex, but the Doctor could tell he was lying. The Doctor used his laser to make his way in the room, burning away the titanium.
“Now see here Dex, a lot of our friends died because of you! Now you can either give us the antidote peacefully or we’ll take it by force,” said the Doctor as he busted in the room.
“I don’t know what you are talking about,” lied Dex. “But now the doors are open and the zombies will get in and kill us all and NO PONY will see this antidote.” He pointed to a beaker full of a greenish-orange liquid on the table.
“I don’t care, I have this Dalek laser to fend off any oncoming hordes, but as for you “Dex”, if that is your real name, you will not live
through this,” said the Doctor. “I intend to pour the antidote into the Ponyville water supply so the zombies can drink the water and return to normal.”
“You fool,” scoffed Dex. “Zombies don’t drink water. They have to be pushed in a lake!” Dex laughed maniacally.
“Or I can put in in a cloud and have that cloud rain it out onto Ponyville. The antidote will get absorbed through their skin and go back to
normal,” suggested Twilight.
“I vote that idea,” agreed Derpy.
“Do what you want, you’ll never make it. The zombie pegasi will chase you, and will catch you, and will EAT you,” said Dex with a chuckle.
“Like you or any of those zombies scare me!” shouted Twilight. “I’ll be back.” Twilight then grabbed the beaker and flew out the lab and headed for Cloudsdale. She went toward the weather factory and gave a factory worker the beaker who then poured it in the machine and powered it on, making it rain down over Ponyville. Zecora busted out of her hut and made her way to Ponyville so the rain will hit her. The group watched what ensues on a monitor.
“I’ll be darned… she did it,” said Dex. Just then a zombie entered the room, it not being outside, thus never being hit with the antidote rain. This pony looked like Trixie, who was also one of the ones that had eaten Roseluck.
“‘Tis a shame, that. But I warned you they’ll make it in,” Dex said with a snicker. This caused the Doctor to shove Dex at Trixie who grabbed him and bit off a large chunk of flesh from his neck, causing him to bleed out. The Doctor then took the laser and shot Trixie and Dex with it. Twilight then returned with a smile.
“I did it! Everypony is saved!” she said with glee.
“Almost everypony,” said Rarity, remembering the deaths of Spike, Granny Smith, Bon Bon, Lyra, Fluttershy, Roseluck and Trixie.
“Right…” said Twilight, upset. “At least we’re alive and many others are too.”
The group made their way back to Ponyville, and saw that all of the surviving zombies had reverted back to normal. They cheered, but were still sad over the loss of the friends that were unfortunate. The day had been saved this time, and as such, the Doctor and Derpy headed back to the TARDIS for their next adventure.
