Audio problem: When Lindsay learns that Tru has broken up with her secret boyfriend and met another guy the same morning, she jokingly whispers to her, "You little slut." The movement of her lips doesn't match at all.
Continuity mistake: The first time Tru lives the day, she has breakfast with her brother first thing in the morning. Harrison goes to put sugar in his coffee and the lid falls off. The second time, they go out together much later (after Tru goes shopping with Lindsay), and Tru manages to grab the sugar lid just before it falls off. But people have been eating at the restaurant all day, so it's not at all likely that the lid would still have been loose. Plus, the same patrons are seen in the diner even though it should be a completely different crowd.
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.
