Other mistake: When Evan finishes talking to the "prostitute Kayleigh" on the restaurant, he goes to his room, which finds his friend having sex with a girl. When Evan demands them to leave the room, he sits on the chair, and opens his diary, but you can see that when he opens it, the pages are empty. He doesn't turn to another page before he begins to read, so he appears to be reading from the blank page.
