Corrected entry: As Tiffany is giving her big speech about the Eagles statistics, she claims that if Pat was rehearsing with her, he wouldn't have gotten in a fight and wouldn't have gotten arrested. How did Tiffany know he got arrested? She was waiting at her house when Pat was at the game and didn't see him until she went to his house. There was no time for her to figure it out and no one spoke of the fact that he got in a fight during the time she was there.
Corrected entry: Tiffany's hair color changes from black to dark auburn back to black during the second act of the film.
Correction: Given the span of time that is covered in the 2nd act, she has more than enough time to get her hair colored. There is no instance of her hair changing during a scene or between cuts.
Correction: She could have been told by phone or text. Remember, Pat was planning to meet her later in the day, so it is likely someone would have informed her he would not be attending.
