Meanwhile, a new promo features Carrie's discussion with Dar Adal and his involvement with Haqqani.

The voice over from Dar Adal says: "Not every choice we make is bliss with moral clarity", and he claims he has received something in return for his actions.

"One adapts to the terrain, we are the nomads at the no-mans land", says the promo.

Adal tells Carrie: "What are you playing at?"

"I call it, give me what I f***ing want," replies Carrie.

Going by the promo, the finale will find Quinn, still mad at Carrie for thwarting his operation in Islamabad, and suiting up for what looks to be a large-scale strike against Haqqani.
