1. whats your favourite season

The scene open up while chad and amy are sitting together having dinner then a unexpected conversation started.

Chad: Hey amy, can I ask you something.  He said nervously.
Amy being confused by what her boyfriend is about to ask, she says " yes of course baby"
Now Chad was always seem to be the joker of the relationship. Chad: so you know we've been dating for a while now. And I was wondering if we could. You know, get intimate with each other.
Amy couldn't believe what she heard. " w-what no, not now Chad I'm not ready" as soon as she says that Chad says " well ill make you ready"

Amy struggling to get Chad off her, she knees him in the balls. Chad in agony falls to the floor, " come back here you bitch" he said in pain.

*Few hours later*

"Baby can you come in the shower please I have a surprise for you" Chad hearing this, gets excited and runs up the stairs "I'm coming baby". As Chad gets to the shower noone was there, but as he turns around he sees a figure all in black with a white mask on.
"Okay babe funny joke" he gets over to the figure , on to be greeted with a nasty surprise. The person stabbed him in the stomach. " B-Baby" he said before collapsing on the floor. Amy comes down to apologise to Chad, but Chad was nowhere to be seen, amy looked everywhere for him but still couldn't find him, so she decided to call his phone.

"Chad this isn't funny anymore " she says as she's petrified.  There was a answer in the phone, but it didn't sound like Chad at all. " hello is this amy", amy even though she's scared,  she replied with, "whoever this is it will hunt you the fuck down, you fuck". The person on the end of the phone, says " come find me then, I'm upstairs " . Amy tempted to call the police,  she decided to go upstairs with a kitchen knife, Only for  her to be treated to her boyfriends body dangling from the ceiling.
Amy screamed, amy tried running out of the house , only for the killer, to grab her and push her to the floor, and put the knife to her heart. " No please don't do this. Please " the killer took its mask off. " You... w-why ?" Then stabbed her in the chest killing her instantly.

"As Halloween approaching quickly,  and new costumes to dress up as- we have some breaking news, 2 people have been murdered moments ago in there house, it's unknown what cause their deaths and what had happened,  by witness where seen"

Who's the killers next victim?
What does he want?

Trevor: "yo,  did you hear what happened, like dam man, i was going to meet then in a few weeks too"

Richard:" yeah bro same , they were good friends to us all"

They all don't know that they could be standing next to a killer.
But the only question is. Why is he targeting his friends?
Richard:" yo Trevor , what's your favourite season"

Trevor replied instantly saying " Halloween,  perfect time to- play pranks on people " laughing as he says it.
They all go into a house party, when Trevor walked out with a bag in his hands...
