Continuity: When Tru and Harrison talk on the phone near the beginning of the day's second incarnation, it is pouring rain where Harrison is, and he's standing under an awning. It's not raining by Tru - or at least not enough to be noticed by the camera or to get her wet, which isn't a problem in and of itself, except that everybody around Tru is carrying umbrellas for some reason.

Continuity: Why does Tru assume that Lindsay would be disappointed by Harrison's gift of a Pez dispenser? When they were shopping together, Lindsay specifically said that she loves Pez dispensers.

Plot hole: There doesn't seem to be enough information about Mark's stabbing for Davis' computer program to determine how tall the attacker was. The main thing that's missing is any information about the angle of the knife's penetration. Without that, there should be no way to obtain the killer's height.

Continuity: After Tru talks to her ex-boyfriend on the roof, she returns to her apartment and asks Luc where everybody went. But before the ex-boyfriend even showed up, everybody was leaving the party and Tru was saying goodbye to them as they left. Then she went to the roof and had her five minute chat with the ex. Why should she be even remotely surprised that everybody has made it out of the apartment by the time she gets back?

Plot hole: When Tru realizes that the yellow-handled knife Lindsay bought was the murder weapon, she gets rid of it. As a result, Lindsay needs to borrow a knife from Tru's neighbor so she can slice vegetables. The fact that Lindsay bought a knife for Tru, combined with the fact that Lindsay couldn't find one later, implies that Tru doesn't have a suitable knife of her own. But Tru served cut fruit to Harrison and his date several episodes ago, so she must already have a knife like that. In fact, pretty much everybody does. And there's no indication that Tru went around hiding all of her knives. In fact, the episode focused on that one, yellow-handled knife to an overly dramatic extent that bordered on inadvertant comedy.

Plot hole: It seems strange that Tru doesn't at any point entertain the possibility that Luc could be the killer. After all, he was the last person left in her apartment before she went to sleep. And if she even thought that she could have done it herself, why does it not occur to her that her boyfriend killed the ex-boyfriend who was quasi-stalking her?

Plot hole: The first time the day happens, Tru tells Luc that Mark called her, and later she tells him that he wants to talk to her, and Luc is fine with that because he trusts her. The second time, knowing that Mark was killed, she decides that she should agree to meet him when he first calls. But she lies to Luc about what she's doing. Why? She knows that he wouldn't have a problem with what she's doing, but instead she tells a lie that conveniently drives the episode's romantic plot.
