Ignore the Screams [South Park AU]

Chapter 10: Possession of Privacy

Gary looked around. "Where am I?" he asked.
"In your head space," Damien said. "You aren't in control of your body right now..."
The ghost manifests in front of them.
"Somehow, I knew it was you, brit!" Damien hissed.
"Vermin!" Gregory growled.
"UNHAND THE MORMAN OR ELSE ILL KILL YOU!!" Damien roared.
"How can you kill me, hmm~ im already dead," Gregory teased.
Damien punched him.
"Ah! Oh, you actually can... I forgot you were a demon," he said.
"Wh-who are you?" Gary asked.
"No time for introductions," Gregory said.

Tweek approaches Gary and Damien, who had just been standing there. He reaches forward to touch his shoulder. "G-Gary?"
Gary grabs Tweek's arm violently.
"ACK!" Tweek screamed, "LET GO OF ME!!!"
Gary laughs, his voice mixed with Gregory's, and he's been fully possessed.
"HELP!!" Tweek screams.
Damien lets go of Gary's back and bites his arm.
Possessed Gary screams in agony.
"YOU BLOODY BRUTE!!!" He screamed, letting go of Tweek.
Damien grabs Tweek and takes him to Craig and Clyde.
"CRAIG, DEERY! TAKE HIM FAR FROM HERE!!! Clyde... go and get rid of that FUCKING phone!" Damien hissed.
Craig nodded and ran away with Tweek and Clyde.
"What about the rest of us, lord?" Beavery asked.
Damien then turned his attention back to the possessed Mormon.
"Help me save his religious ass."
