Plot hole: Throughout the series, auxiliary characters are always far too willing to give all kinds of information to Tru. Doctors and registrars constantly give her privileged information about patients and students. Tru is often able to retrieve information like addresses and phone numbers from people's service and utility companies, when normally you must verify your own information before they will even talk to you about your account. Of course there can't be an episode if Tru doesn't quickly find the person who asked for her help, even though she doesn't usually know much more than their name, but it's still a bit conspicuous.

Continuity: In Season 2 episode 4 (Last Good Day), Davis is pouring wine into a glass for quite a long time when the woman (can't remember her name) squeezes his leg. He drops the bottle but the glass has hardly any wine in it.
