Character mistake: At the end of the episode, after Sarah has been tricked into revealing her plan and is rather obviously going to go to jail, Tru tells her that she "should have taken half," meaning that she should have settled for half of Andrew's money in a divorce instead of trying to get all of it by having him murdered. But Tru seems to be forgetting that Sarah has been trying to divorce Andrew all along, and it's Andrew who has stood in the way of that. Sarah would evidently have been perfectly happy with half, but Andrew prevented it from even being on the table for her, so Tru's comment doesn't make any sense.
Continuity mistake: The second time the day happens, the man stands up in the restaurant to profess his love to his girlfriend almost immediately after the waiter drops his tray. There is only about ten seconds between the two events, but the first time it all happened, there was a gap of nearly thirty seconds.
Plot hole: When Marco brings Andrew's corpse to the morgue the first time the evening happens, he says that Andrew was died "in his ex-wife's house." However, during the second instance of the day, it is eventually revealed that Sarah is actually still married to Andrew, and they are just separated. Sarah may have lied to Harrison about that, but the police would have gotten accurate information. In fact, when Sarah calls the police (the second time), she refers to Andrew as "her husband."
