Three people... all dead... and all connected... to P&E.
1) Phillip killed Chris Amador unintentionally. Amador got in his face over something really minor that ended in his death - it wasn't because he was FBI... it was because Amador used his FBI cred to play heavy with Phillip and Phillip outmanned/outplayed/out-fought Amador.
2) To avenge Amador's disappearance (and later, death), Stan incorrectly, but intentionally, kills Vlad. Vlad really had nothing at all to do with Stan's partner's disappearance (and later, death) but that didn't matter to Stan at all. He was out for blood and wanted someone to pay. Vlad was a convenient target because, in Stan's mind, he's Russian so of course he's involved. Had nothing ever happened to Chris Amador in the first place, Stan wouldn't have had a disappearance/death to avenge and Vlad would still be alive.
3) Gregory chose to go out on his own terms. It was a member of his crew that got fingered for bringing in the car for crushing / pawning the ring that Amador always wore. Gregory knew there'd ultimately be a price to pay for his traitorous ways and while he was loyal to the very end, he paid the ultimate price for getting involved with Elizabeth and agreeing to be a recruit.
Three people dead... and all connected to Phillip & Elizabeth.
At the end, it was so heartbreaking hearing that beautiful, slow, haunting rendition of To Love Somebody. Incredible choice of music and a great way to conclude the episode with a powerful montage of images/scenes.
I usually delete each episode after watching but this one? This one was a keeper!
