When sitting in the diner discussing what to do, Leilani and Jibran are served milkshakes which can be seen in front of them. As the camera goes back and forth during their conversation, Leilani's milkshake turns into a plate of french fries. Neither character ordered french fries.
The "milkshake container" was obviously empty when played with by Ji then at least half full when he drops the mobile phone in it.
Just like every other movie, the "butterfly" bandage on Ji's right temple is not pulling the edges of the wound as it should, thus rendering it useless.
The dead frat boy in the hall is clearly still breathing.
