What plot development?
Honestly, there were really only 2 major plot points in the episode I saw...
Sensa Confronting Dani about what about the north when everything is done
And Jon telling Dani, he’s her nephew and legitimate heir to the throne
I guess you can officially realizing Cersi wasn’t sending anyone could be considered a plot point, but you knew as a viewer that wasn’t happening already.
Same thing with the fleet sailing back to the Iron Isles... yes the characters didn’t know that until this episode, but the viewer knew.
There really wasn’t much more plot development... Just tying up lose ends, and some fan boy coming to Jesus before a lot of these characters die.
You and Borges should get a room
