“I thought it was a satisfying ending…Alicia did whatever she had to do and rode over anyone in her way to get what she wants. In saving Peter she became just like him. The slap to echo episode 1 was well placed therefore. Perhaps Alicia’s shock that Diane would take total betrayal personally - she seemed ready to greet Diane as if nothing had happened - will be (we’ll never know) a wakeup call.”
OMG. You nailed this.
