Carrie returns home to deal with what she saw in Islamabad on the season finale of Homeland. "Long Time Coming" is the 12th episode of the show's fourth season.
Alright, admittedly it's a little awkward with Brody just left hanging and Carrie carrying his baby, but Quinn has been there for Carrie in many ways knowing this all along. He considered quitting over what she went through! They've always shared tension and he's a better match for her than the married, (dead) terrorist.
Carrie: I missed something once before. I won't, I can't let that happen again. Saul: It was ten years ago. Everyone missed something that day. Carrie: Everyone's not me.
