Damn brehs....LF definitely expected Tyrion to be blamed for Jofferys murder. So he expects Tyrion will die or be banished so Sansa can marry again. He planned to marry Cats sister to take over that castle and it's ill defenses and kill her because she talk too much and is a liability..
That would allow him to marry Sansa and control Winterfell while still being in the good graces of the Lannisters which occupy the thrown that he put in massive debt. So Stannis (with the iron banks backing) and the Lannisters will duke it out while LF is chilling....only to come in a swoop up and attack while both powerhouses are weakened....
WTF is this nikka planning next
.....this shyt is chess brehs..
