Changes in Script

 As we couldn't find a house for the final shooting so we decided to shoot in a basement parking, so obviously we had to change the script too.

here is the new script;

 New Script of The Film Opening 

EXT - I-8 PARK - DAY

 Ali is leaning on a tree, holding his diary in his hands, reading out of it, something that his other personality had written.

ALI

You have to kill her.

No... I can't kill her.

Ali cracks his neck rapidly, and switches personality. 

ALI

I can kill her, I will kill her.

EXT - PARKING LOT - DAY

Sarah is walking up the stairs, to her car in the parking lot, talking to her friend over the call. 

SARAH

I was never able to understand him. Good riddance, honestly. 

He was so unreliable. He'd act a certain way, and then the very next minute, he's a completely different person. And I can't even recognize him anymore.

Ali has already heard the conversation between her and her friend. While she is taking the keys out of her bag, she sees his reflection in the car window, he's standing behind her. She gets startled, drops the keys and turns around. 

SARAH 

What are you doing here?

ALI

Did you really think you could get away from me so easily?

SARAH

What do you mean?

Ali pulls out a knife that he was hiding behind his back. Sarah sees the knife and tries negotiating, while still panicking. In a state of panic and urgency, she attempts opening the car door.

SARAH

Look, we can talk about this! We can talk about this! 

Ali slowly steps closer. then lunges at Sarah, grabbing her by the upper arm, and pulling her away from the car. Sarah fights back, pushes him and tries to free herself. After she breaks free for a while, he drags her back, and thrusts her against the car door. He raises his hand to stab her but she holds him back by the wrist; attempting to push her off. In this tug of war, one of them gets stabbed, indicated by the blood splashes on Sarah's car.
