This kind of felt like a slide for the show, the episodes before now had been getting better each time--but this one was too straight forward (even taking the twist into account). However I think its nessicary to address some of the comments I'm seeing in this thread.
First, in regard to the show being written careless--I flat out disagree. The revelation about her mother has been set up since nearly the first episode, and built up from there. I'll admit that when Davis first figured out that Tru could do what she could do I thought it was slipshod writing. But now that I know that he knew Tru's mother it makes a lot of sense (yeah, maybe I should have seen it coming). Other little touches that I think go against your point involve the way Tru's changes affect the people around her. Yeah, sometimes things go like she thinks they will when she tries to help her faimly--but other times they go the oppisite. The way the plots are put together is also impressive. Considering that the show could be nothing more than a lame crime show I've been impressed with the way the writers have played with the stories (things like not having her save the person she was supposed to, or even ending up not being able to save them). But even more impressive they've actually imbued the show with a theme and issues about fate and playing God that I have to say are downright interesting and full of excellent conflict for the character of Tru.
My other comment was on the person who said that Tru's character lacks any amount of tact. Yeah, I've noticed since the first episode(although she has gotten somewhat better). It would bother me, but they have been downright consistent about it. It really is just who she is (and is further reflected in her personal relationships, which tells me that it isn't just a plot device that pops in and out of existence).
Anyway as for this week's episode I felt we got some good stuff(mostly in those last minutes of the show). But for the most part there were little things that just didn't work(the show in general may not be careless, but this ep was). Things like the timeline not working out to be the same the second time around bothered me as I was watching. The main characters were as good as always, but the side characters lacked interest for me.
But then you get the moment at the end that makes it all work(for me at least). I'd never actually reliazed before now that Tru's mom had the same thing (yeah, it was built up since the first ep--I see that now--but just never really got it until this moment). The other good thing in the episode was, as others have already said, the reporter--we should see interesting things from this.
Also, since I'm writing this after seeing "Daddy's Girl" I can say with confidence that the show will be going back to its previous increase in quality.
