Paul is death (my version)

Help for Paul

POV John
I drove briskly to Paul's house and saw that the lights were still on in his house, so he was still awake. I opened the door with the key and walked in. I looked for Paul but couldn't find him anywhere. Maybe in the basement... who knows?
I opened the basement door and heard screams and rumbles in agony. i ran as fast as i could down the stairs where i collided with paul."Paul what's going on here..?!" I yelled at him and when he just looked shocked I ran on. He tried to stop me I mean nobody can stop John Winston Lennon.
Suddenly there was a door in front of me that I kicked open. My knees started to tremble and my vision almost went black, it was so bad what I had to see.
"Paul!!!" I yelled and he looked up at me with a blood smeared face while holding his leg to probably stop the heavy bleeding. "John...help me...please" he started to stammer.
I ran to him and looked at the wound. A bullet wound. ,, How? I just met Paul on the stairs and where's your mustache?" He replied quickly and panicked, ''An impostor John''
Paul's face slowly grew pale and his eyes dull ''PAUL! DON'T SLEEP NOW, PLEASE I NEED YOU!!!" I started screaming in panic.
"John... take care of the guy and not me. Leave me here and catch this psycho... before he does anything else to anyone else." Paul began to mumble in response.
,,NO! I won't!" I yelled. Paul pointed to something behind me with his shaky hand, then I saw the guy standing in the doorway smiling contentedly. I lunged at him and knocked him unconscious.
I quickly ran upstairs and called the police and emergency doctor. Later, almost the entire street was lit up with lights from the police cars and the guy, who I was told was called Billy Shears, was taken away by the police.
