Plot hole: Richard tells Tru that Carl periodically comes around threatening to exact revenge on him unless he pays him off. The audience eventually finds out that Richard hired Carl to kill his first wife, so it makes sense that Carl can demand money from Richard and not face any consequences. But why does the story make sense to Tru? The way Richard told it, Carl has nothing on him, so there's no reason for him to be paying him off. Tru should ask her father why he doesn't simply get a restraining order.
Continuity mistake: Harrison and Melissa are in a poker game. In the scene where her flush beats his pair of fives, they each have the eight of spades in their hand.
Continuity mistake: When Tru, Jack and Davis visit the car salesman she says that she worked at the 'county', but on their jackets it says 'City Morgue'.
Chosen answer: The next episode shows that Tru didn't meet Luc after all, even though she should have been in work by the time he showed up. I think the answer is that the writers don't actually know.
