The girl that was in the truck that helped them was Duncan's mom's assistant? Can't really remember her role in all of it. Will need to go back and watch.
Yes, she was -- and, you may recall, she is Celeste's illegitimate daughter from years ago, making her the baby's aunt.
I really liked this episode. At first, I was prepared not to, because when Lamb arrived to arrest Veronica at the beginning I thought, "How many times can they recycle the plot where Veronica is arrested/searched/accused of something she obviously didn't do?" And yet the plot circled back on itself numerous times, with Lamb actually being smarter than we think, but also being used in a way we don't expect, such that he is both right and wrong simultaneously.
I do agree somewhat with the complaints about viewer misdirection. Much of it was warranted and defensible, but it probably did go a bit far. Also, it's becoming a bit awkward with the way the part-time characters like Wallace and Weevil are shuttled into and out of the story, and mysteries and drama around them come and go with their presence or absence. But those are minor quibbles. I love the way Thomas & Co. continue to explore Veronica's moral ambiguities, and how -- finally -- they blew up in her face with Keith. That was an exceptionally well-played sequence, and Veronica richly deserves whatever fallout comes from it.
