I just watched the 6th (5th if you count Genesis part 1&2 as 1 episode) episode and I have to say this episode moved me at one point.
SPOILERS!So at the beginning, a soldier is attacked and killed by a Nykoraptor and, at first, it is passed off as a slip up on the soldier's part but Jim finds claw marks on the inside of the door, which he assumes means someone trapped it in there to kill said soldier. Well he investigates, finds out the soldier was having an affair with this married woman (scandal in Terra Nova!!

). Well, she is hesitant to answer questions about their relationship, which she continually denies. Then, the guy who she married (she married him because he won a lottery ticket to Terra Nova. Terra Nova version of a gold-digger

). She starts talking to him about how Jim was asking question about the deceased and he angrily tells to "just shut up!" He say he knew about her and Foster (the soldier) and that he killed him!
So Jim interrogates him and he gives elaborate detail about how he did it. Jim feels that something is not right with Milner's confession after Elisabeth and him get into an argument which ends with her stating, "Like no one's ever had reason to falsely confess."
Taylor buries his soldier and passes punishment on Milner, banishing him from Terra Nova. This was the moment that almost made me cry. It was just moving and the best scene from the show so far. There were people who did not agree with Taylor's decision.
Jim finds Milner out in the wild and he finds out that Milner did in fact falsely confess because he did not want his wife (Rebecca) to be thrown out in the wild by herself because she murdered Foster (or did she?). They confront her and she says she did not kill Foster. She had broken up with him because he was a jerk and he only cared about his friends and...gambling! Card games were played at Boylan's bar.(more scandal) Jim checks Foster's financial records and finds someone who owed Foster a lot of money. They go to Boylan's and arrest him. Boylan has written records of all the money from the card games and Jim goes back to the bar to find them. They aren't there and Reynolds comes in with a bloody nose and says Boylan has escaped. Jim, Taylor, and one of the soldiers, Curran, follow Boylan's signal outside the gates but they don't find him. Then, the twist happens. It turns out that the soldier Curran owed Foster the money and killed him because he couldn't pay Foster the money he owed. In the end, he is banished without a weapon (Milner was given a weapon).
Oh and Josh (the annoyingly whiny b*** of a son) meets Mira and agrees to an unknown task to get his girlfriend to Terra Nova. I mean, this boy is stupid. He is willing to risk the entire colony in order to get his girlfriend. Poor Skye who, although volunteered to help, is clearly reluctant now that Mira is involved.
The twist came as a surprise to me. I honestly thought it was Boylan. I rewatched it and noticed a dead giveaway. At one point, they show Curran fidgeting and looking nervous.
And last note, the Shannon family has a new pet: a baby Ankylosaur! It's hatching scene was nothing compared to the Velociraptor hatching in Jurassic Park (the egg was simply plastic and hollow with a Ankylosaur robot inside).
Terra Nova is starting to get interesting. It took long enough. Halfway through the 1st season already.

Looking forward to more Terra Nova.
Edit: I forgot one major event and a subplot. When Elisabeth is autopsying the body, she finds Gallusaur blood (favorite food of the nykos) which turns out to be from bait that was hung in the shed to lure the nyko in.
Subplot: Elisabeth does surgery on the unhatched Ankylosaur because one of its front legs is fused to its neck.
