Ahhhh, Some of what I've got has spoilers...
The show has a lot of relationships in threes:
Mackey/ Corrine/ Cassidy
Shane/ Mara/ Jackson
Billings/ Allison/ Maggie
Dutch/ Rita/ Lloyd
Aceveda/ Pezuela/ Beltran
Not to forget of course,
Mackey/ Shane/ Ronnie, who were close like brothers earlier but have split. Will Ronnie kill Mackey to stay free? Just a couple episodes ago he was more cold blooded than Vic.
None of these relationships are stable. There is so much drama here I wonder how they can fit it all in four eps... what will go wrong next? Each of these relationships are full speed ahead for disaster.
I lost count of all the lies, here and now it's easier to keep track of who's being truthful. Julien doesn't trust Ronnie. Claudette doesn't trust Ronnie either and clearly is not fully buying "We just found out Shane killed Lem".
Corrine can't trust Vic or Mara ( not to mention Shane ). Corrine is a sort of center of gravity in this storyline; her actions will determine the outcome more than any one else; and... she doesn't know she's at the center. She thinks Vic is.
Vic has been occupied and hasn't noticed Danni took off with Lee ( yet another threes relationship ). What's with the Confederate kids? ( Lee, Jackson... )
This season is a little like the one with Mackey vs Kavanaugh; this time the tension is all internal and the battle of wits is for higher stakes. I sometimes forget this is fiction and not hidden camera footage of real events.
They're going out with a great season. I've no doubt I'll remember the conclusion for a long, long time.
