Great opening voiceover.
Emotional Carolyn and pragmatic David. Emotionally and clinically detached David is still on a mission to get rid of his father for good. So much so that he's willing to learn the mathematics of tide charts. It's disturbing really. Their conversation is mostly typical of them. At least Carolyn isn't being hateful toward him. I think she is too depleted unless she's actually grown up a bit in these few weeks.
Sheriff Patterson certainly treats the haves more gently than the have-nots. He wasn't nearly as demonstrative with Roger as he is with Sam. He came at him with both barrels blasting. I guess we'll see just how gentle he'll be with Roger in round two. He's certainly not stupid having already figured out that Roger and Sam had the most to gain from Bill's death, thanks to Burke.
Why is David so dirty? Surely not from the rug?! I guess it's from playing outside earlier in the day? Nice touch of realism. He was more than eager to fetch his father for questioning by the sheriff, lol. I expected him to say, "Are you hear to arrest my father for Mr. Malloy's murder?!"
As Carolyn has stated more than once - Good old Joe. They'll probably get into an argument on their trip to nowhere before he gets to hogtie her. I say - Poor old Joe.
