Rainbow Dash sat on the cold metal table, looking around curiously. She had to be careful not to move too much, because her neck was bandaged. The room she was in was pretty plain, the table she sat on was in the middle of the room, and a heavy iron door with a tiny window was the only other thing she could see. There was also a mirror spanning the length of the wall behind her, but she didn't turn around to look at it.
The mirror was only one way. On the other side of it was a dark room, where two ponies stood watching Rainbow. One of them adjusted his glasses and straightened his lab coat. He spoke to the other.
"Explain to me one more time what happened."
Twilight sighed. "For the twelfth time, we were walking through Ponyville's Cemetery because it was a shorter path than going around, when some crazy homeless pony jumped out and bit rainbow Dash in the neck. I used my magic to stop her from bleeding out, then reported the incident to the police while I brought her to the hospital.
"And what happened to the homeless pony?"
"No idea. He stumbled off after he bit her."
"Twilight, I'm going to tell you something, and I need you to believe me, no matter how strange it sounds."
"Alright?"
"That homeless pony was a zombie. Rainbow Dash could be in a lot of danger right now."
"Wait, what?"
"You heard me. A zombie. The way I see it Rainbow Dash has a few days if she's lucky. She seems to be doing fine now, but soon she'll get sick, then die, then come back."
"Doctor, do you really expect me to believe this? Zombies are nothing more than a myth." The doctor turned to Twilight, his eyes burning with memories that no pony should have to deal with.
"Princess Celestia doesn't tell her subjects everything, Twilight. I bet you didn't know we're fighting a wave of these things coming from the north. We don't know where they came from, but they are ruthless, brutal, and ave no moral restraints. We suspect dark magic. I know, I've been there. I've studied them, fought them myself. I've lost friends to them, and now they're here in Ponyville. We may not have much time."
Twilight and the doctor continued to argue in the dark room, meanwhile, Rainbow Dash was beginning to feel feverish, and was getting the strangest craving for some brains.
