A/N: Mitch looks like the picture. Outfit and everything but his hair is a bit longer.
Scott's PoV
I was walking down the streets of Beacon Hills. It has been 10 years now since Stiles went missing. Everyone thinks he is dead but I want to believe he is still alive. I miss my best friend. The last time I saw him was when we had a fight about him killing. But now I know that wasn't him, he was trying to escape. I feel so bad. I keep trying to find signs that he is still alive but nothing. Me and the pack miss him so much.
So here I am walking down the street. But I smell something a bit familiar with a lot of death and blood. I look around to see the back of a grown man. He had short but a bit long hair, a green long sleeve shirt, jeans and a duffle bag. He was heading towards something or was it someone? He turns his head over his shoulder and I see that he is wearing sun glasses and that he has some scruff. But he seems so familiar.
So I follow him. I think that he knows I am following him. I see that he is heading to a hotel. So I just turn around and go back to my mom's.
"Mom I am home!" I yell walking into the house to see Sheriff Noah Stilinski.
"Scott do you remember back 6 years ago where Ibiza, Spain had a terrorist attack?" My mom ask me.
"Yea. I remember hearing about that. Why?" I ask looking over to The Sheriff.
"The news finally found a video of the event." My mom say and hits play on the T.V.
The video shows waves of the beach and a voice could be heard: "Here we are in beautiful Ibiza, Spain." The phone moves to the beach. "Beautiful Sand. Beautiful waves." You could see the waves crashing into the sand. When he spoke showing his yellow swim shorts. Then to a girl: "My favorite shorts. And my favorite girl, who is about to get...Oh, my God!" He says as the wave comes as the girl says: "Hey! Come on, give it to me." The guy simply states:"No! Stop! Come on!" In a happy tone. "Mitch!" The girl says reviling the name of the guy who is filming. "This is great!" Mitch says. "I'm serious." The girl says. Mitch just states: "oh. Oh, my God. That is so cute."
"Does he sound familiar?" Stilinski asks. We all shrug and continue to watch the video.
"Honey, this is like...Let me film for just a couple minutes." Mitch says just as the girl smiles. "It's like we're honeymooners." Mitch says again. "Oh, my God!" The girl says laughing as mitch sings:"Honeymooners" and the girl questions him "honeymoon?" Mitch says "yeah." Thats when the girl says: "we're not married." Then goes under the water.
Mitch then pulls out a necklet with a ring on it and the girl comes back up. He says: "Katrina Harper..." giving the name to the girl, now known to be Katrina, he continues:" You're my best friend in the whole world. Oh, my God. Babe, stop it. You're gonna make me...If you get emotional, you're gonna kill me. I'm trying to get through this, babe." He continues as the both of them laugh then Mitch finally says:"I love you more than anything. Will you marry me?"
Katrina says: " Oh, my God! Yes!" And Mitch asks "Yeah?" "Yes, Mitch Rapp. I'll marry you." Katrina says as Mitch puts the necklace around her neck. "Sorry, it's hard one-handed." Mitch whispers. "You like it? It was my moms ring." He asks her. "I love it" Katrina says as Mitch says:"I love you." Then Katrina kissing Mitch.
Mitch brings the camera up so you could see the both of them.
The sheriff pauses the video and we see that Mitch is Stiles.
"Stiles?" Noah asks. And continues the video stunned.
"I'm still..." "Are you filming? Oh, my God!" Katrina yells at Mitch. "Yeah, I'm still filming. I'm trying to get this." Mitch says. "Come on Mitch!" Katrina says laughing.
The video continues to where Mitch goes to get drinks then the Terrorist attack starts. You could see everyone getting shot. And you cold see Mitch and Katrina getting shot on the beach right next to each other. Then the video ends.
Third PoV:
"Stiles...he did die!" Melissa says looking down.
"That was 6 years ago!" Noah says staring at the T.V. "And why was Katrina saying his name was Mitch Rapp?"
"He must have changed his name 10 years ago. That makes sense why we couldn't find anything on him." Melissa says trying to contort Noah.
"So he is actually dead. My son has been dead for 4 years!" Noah says but when he looks up at the T.V. It was paused on all of the people who have died that day. But there was no Stiles Stilinski or Mitch Rapp.
"Wait he lived! Look it doesn't have His name up on the list!" Scott said trying to bring joy to the situation.
"We have to find him!" Noah says.
