When Josh and Haley run into each other and spill papers everywhere, they pick up all the papers, but 1 that is visible when Haley storms off. It is to Josh's right. However, after Josh reads his texts and moves on, the paper is no longer visible and he walks right over where the paper had been.
Around minute 66, Hayley was on the phone trying to text the Poet and calling Elisa, but her phone was upside down the whole time.
