The Mysterious Person (Don't know what to call it. Might change it later)

Just the beginning

"SWAGGI! GET UP!" A familiar voice makes me jump.
"WHAT IS IT?!" I yell back.
"Nothing, EXCEPT YOU'VE BEEN SLEEPING FOR 6 HOURS!" Wolf shouts at me.
What I have? I must be really tired... "Where are the others?"
"Downstairs!" She replies. She is always so cheerful, but sometimes it can get annoying. "What time is it?" I ask.
"6pm"
"WHAT?!" I said in shock.
"Yup, I told you, you've been sleeping for 6 HOURS!"
"Thanks for waking me up. I'll be down there soon."
"Okay no problem!" She got up and out of the room. Whew.

I sit on the edge of my bed. 6 hours? Seriously? I hear a sudden clash from downstairs. Is there something wrong? Better go and check. As I open the door another clashing sound came from downstairs.
"Err, is everything alright?" I call out while going down.
"S-Swaggi! C-come and look!" Cash stammered. She sound frighten which made me pick up pace and go down the stairs faster. "What? What's happening?!" I said in confusion. "Th-that!" Sqssy pointed

I follow where Sqssy was pointing. It was just a bottle with roll up piece of paper inside. Surrounding was broken glass. "Why is there broken glass?!" I question.
"It came flying through the window." Arnold answers.
What?! The window!! I look at the window to my right. Behind me I could hear Wolf and Cash panicking. "I'm gonna use the bathroom... Be right back" Wolf says, going up the stairs. I pick up the bottle and open it. I tilt the bottle to one side, The roll of paper slip out. I unroll and stared at it in confusion.
"What does it say?" CoolDude ask me. "It's says... Don't get caught..."

"What?" Hero says to himself "We better be careful. Someone is messing with us."
"Bruh, ima give them a good fist to the face if they mess with us!" Sqssy says with her fist in the air. I think to myself for a minute. Don't get caught? BEEP! I feel my phone vibrate in my pocket. I pull out my phone, I got a text message from someone, someone I've never talk to. "Someone should go check on Wolf... She's been gone for a while... Hehehe"

What?! "WOLF!" I shout I rush up the stairs.
" AHH! Someone help me!!!" I hear her scream turn into muffles.
"WOLF, IM COMING!" I no longer could hear her voice. "Wolf?!" The others follow me as I kick the bathroom door open. Silence greeted me. "Wolf?" I call out. She's gone.
"Where's Wolf?!" Cash question.
"SHE WAS IN THE BATHROOM! Where did she go?!" Arnold cried.

BEEP! Another message. "Too slow."
"WHAT DID YOU DO TO WOLF?!" I text back. I assume they did something to her. I don't know why I'm texting them but why are they doing this.
BEEP! Another message. "Hm, sad that you left your brother all alone downstairs..."
"COOL!" I hear Cash scream. I look down where we were before. Cool wasn't there anymore. "EVERYONE STICK TOGETHER!" I yelled. "IF WE SEPARATE THEY WILL GET US!"
"Oh my god, what is happening...?" Sqssy says trembling.

BEEP! My phone went off again. "That doesn't change anything, We will get all of you no matter what..."
