Ghostface in cobra Kai ?!(season 1 mostly )

Why is he stalking me?

As they took samantha LaRusso (Miguel's girlfriend )to the hospital after she got stabbed really badly. The doctors told them that they will have to keep samantha at the hospital for a couple of days untill she gets better because she lost a whole lot of blood. Hey Sensei Miguel starts to leave a message at senseis phone saying that he needs help and more protection just in case he has to really face the killer.
Miguel then decided to trick hawk and demetri by telling them that he's going home but instead he'll be following either  Hawk or demetri just in case they know something. But since he needed help because he neeeds to track two people and he can't do it himself he decided to call moon (Samantha's friend )for help.Moon came and helped Miguel by tracking her boyfriend Hawk/Eli while Miguel took track of demetri as what he's doing. Miguel followed demetri home and noticed that he wasn't that suspicious after all he didn't leave his house nor called someone,as Miguel was "stalking" demetri out of his window Miguel's phone rang his heart literally dropped and he hid himself underneath the bush. Miguel was scared for his life even tho demetri is one of his best friend. Miguel decided to make a run but he thought it would be a stupid decision and it'll make himself suspicious. As demetri came outside his house to check who it is Miguel decided to run through Demetris back gate.demetri noticed someone leaving his back gate and decided to scream I'll call the cops if I ever see you again!! Miguel noticed that it was moon that had called and it was such a bad timing because he could have been caught peaking in demetris window. Hey moon what's up Miguel said while running ?, are you running mi?moon asked yeah yeah quick now what's up! Moon replied well I was "stalking" hawk and I think he's in the clear he was literally watching movies till 12 then he went to bed. Miguel replied okay thanks and ran back to his house. He called Danial LaRusso asking if everything is okay? Daniel replied I'm just sitting here waiting for my daughter to get better I'm fine hbu? I'm okay do you need me to stay the night or the morning? Miguel asked LaRusso replied it's okay just come over in the morning because I have to go to work, perfect I'll be there at 8. Demetri was wondering In his back yard thinking who would stalk him and watch him through his window. As demetri was walking back and forth while thinking he stepped on a bracelet which was blue and he noticed straight away that it was Miguel's because he and hawk have the same one and they promise to never take it off,so as Miguel was running he must have dropped it while opening the back gate.Demetri decided to go to hawks house and talk about this situation because Miguel is acting suspiciously nowadays. As Demetri approached Hawks house he knocked rapidly waking Hawk out mid dream. He quickly went to the door and opened it hey what's up demetri are you okay?? Hawk asks demetri as he was standing there with a "I have something to tell you" face. Demetri noticed that hawk was wearing the same blue bracelet that they all wear so now demetri was sure that it was Miguel out side his house.Demetri took the bracelet out of his pocket and said I found Miguel's bracelet out my backyard while he was stalking me before his phone rang which made me come out to find someone running out my back gate until I found Miguel's bracelet I wasn't sure who it was. But the real question is why is Miguel Diaz stalking me and what does he want to see out of my window??
