Jaime comes home, has Brienne arrested for her own safety (though she does not understand this), shags his sister in the church next to his son's open coffin, tells her he'll have to think about whether or not to kill his brother for her, and goes to see his dad.
His dad wants him to break his vows to the Kingsguard, marry his son's widow, and take up residence in the family castle, and disowns him when he refuses.
It's just an ordinary Lannister day.
Oh, and GREGOR is now in charge of Harrenal having chopped off Vargo Hoat's hands and feet, which is only fair.
