This post contains spoilers from Game Of Thrones Season 7, Episode 5. It's been a long time since the Lannister siblings have seen each other. Not nearly so long as the Starks, but still. The last time Jaime saw Tyrion, he had just let him out of his cell to escape his execution the next day. Now, he's back again in the bowels of the Red Keep, as Tyrion and Jaime reunite on Game Of Thrones for the first time in three years.
It's been a long time since Tyrion Lannister left King's Landing tucked away inside a crate on a boat next to Varys as the bells rang out the announcement of Tywin's passing. Since then, he's drunk he way across Essos, fought Stone Men, got enslaved, got un-enslaved, ran Meereen for a while, became Hand of the Queen, and is now at war against his sister. Meanwhile, Jaime has lost his father, his kids, and nearly his own life.
But Tyrion, for all his failures on the battlefiled, had impeccable timing when he sent his note to Bronn. After all, Jaime only just learned that he made the right call back in that dungeon in Season 4, by letting Tyrion go free. His brother was innocent.
And Tywin knew it. He didn't know it was Olenna, but the fact was, Tywin didn't care. He was using this as a show trial to kill his own son. Frankly, their father got what he deserved. And while that argument wouldn't ever fly with Cersei, since she'd do the same in a heartbeat, it does with Jaime. (Actually let's be real, Cersei wouldn't bother with the show trial.)
It's good to see the sane Lannisters back together and just maybe aiming for the same ends. Now whether the plan to capture a live wight to present to Cersei as proof will work out? That's still something I need to see to believe.
