Other mistake: Daric asks Ben to do "by tomorrow" a cheat sheet and get a 50 for it. Ben angrily crumples the sheet. At leas a day passes by, but there' a scene follows and Ben returns that same cheat sheet, neatly folded. He could have course have just copied it back on a pristine sheet, but he certainly didn't deliver it on the day he was asked to, but Daric makes no comment about it. (00:23:10)
