"Twilight?"
"Yes, Spike?"
"Something is wrong with everypony."
For a few days, nothing out of the ordinary happened. But over those few days, Twilight noticed certain ponies were starting to look sick. She took notes on this.
First, their eyes began to turn white.
Second, they lost the ability of speech.
Then, they turned pale.
And last, they grown an extreme hunger to anything they can find.
"I noticed, Spike. And I'm keeping a close eye on it."
That's the day things got bad again.
It was within that moment, that Twilight saw one of the sick ponies bite other pony.
It was that moment that Twilight knew what had happened.
"They've turned into zombies! That's not possible! That's-"
That's what, Twilight?
"The Zombie disease is an SCP, isn't it?"
"Again, Twilight?"
"Yes. It is time to destroy the zombies."
"How?"
She looked at Spike, with an adventurous smile.
"We need a doctor, for a disease, right?"
Where's the good Doctor when you need him!?
And he's back in black!!
