Better than the actual finale.
Awful. I can't quite make sense of his master plan for this season either. Wait for Jon to fuck off, manipulate Sansa into executing her sister, then say "look at this shit?!" to banners at large and appoint himself new king of the north? What?
Not that I think it's good but I think this was basically his line of thought.
"Sansa hates me for selling her to the Boltons. How can I get her back to trusting and needing me again like she did in season 4?"
"Well I'll fan the flames of distrust between her siblings and whisper to her ego and convince her that what she really wants is power and to rule the north."
"Then when she sees that she can't trust her bastard brother and murderous sister, all she'll have is me as her confidant and she'll trust and need me again."
And then after she is queen with her family removed, he could look for another round of chaos to gain more power in the south.
Basic gist of what I think they were going for, obviously the execution was really clumsy and stupid.
