It was a perfect murder, planned perfectly to even the slightest of details. You, Billy and Stu took turns in using the cheap ghostface costume to gruesomely kill some teenagers across Woodsboro and start the panic and paranoia, then stealed the phone from Sidney's father and made the calls from it so it would frame him, then, finally, kill Sidney and the rest of the friendgroup in the party at Stuart's house then leave the phone on the floor framing Sidney's father for the murder of everyone except you three, who he gave as dead.
So, while you were holding a panicked and crying Sidney by the collar of her shirt, Billy and Stu were bickering about who got to stab her first. You were starting to get irritated, so you shouted at them to stop, but before you could even do anything, you saw a twitch in Billy's left eye. The next thing you knew Billy had swiftly buried the knife in Stuart's side, who cried out in pain —grabbing his gaping wound—, stabing him just enough for the pain to shut him up.
"shut the fuck up, you sissy" Billy spat bitterly as he saw Stuart giving you kicked puppy eyes as he whimpered from the pain, his eyes glossy as the hand he was using to try and stop the bleeding got coated in his blood. "I'm killing the bitch, you go and lay somewhere in the house for when the police arrives" he stated finally as he turned around with the knife stained with Stu's blood and snatched the wailing Sidney away from your grasp.
Stu made a small gargled whimpering sound as he brought his shaking free hand to his mouth, coughing —or throwing up— thick crimson blood onto his palm while he looked at Billy with narrowed and tearful eyes. His body trembling from the pain of being stabbed "I- I can't" he whimpered, his voice weak and feeble "dude, you pinched me too hard.." he whined pitifully "I think m'dying.." he added as he looked at you with puppy eyes from underneath his wet eyelashes, his lips stained by his blood.
