As Game of Thrones' sixth season nears its end, many long-simmering feuds are beginning to boil over.

In Sunday's episode "No One," Jaime (Nikolaj Coster-Waldau) had to decide what to do about the Siege of Riverrun. Cersei's (Lena Headey) battle with the Faith hit a huge hiccup. And Arya (Maisie Williams) and the Waif's (Faye Marsay) feud came to a bitter end.

Oh, and a whole bunch of people died. Read on for the craziest moments from "No One" below.

Braavos: Fresh off of getting stabbed by the Waif, Arya runs to Lady Crane, who tends her wounds and provides some milk of the poppy to help her sleep. But sadly, by the time Arya wakes up, the Waif has already tracked her down and killed Lady Crane.

Despite being stabbed in the gut the day before and having just woken up from a monster nap, Arya displays insane parkour powers and leads the Waif on a wild chase through the streets of Braavos, ultimately leading her to that tiny dark room where Needle is. As predicted, Arya blows out the candle and relies on her blind fighting skills to add the Waif's face to the Hall. Upon seeing this, Jaqen (Tom Wiaschiha) declares that Arya is finally No One, but Arya is like, "On second thought, I'm actually Arya Stark. Peace out. I'm heading to Westeros." Or at least that's her plan if she doesn't die of her multiple gut wounds first.

The forest: The Hound (Rory McCann) doesn't waste any time before fulfilling his revenge mission, quickly tracking down the members of the Brotherhood Without Banners that killed Brother Ray and axing them to death like it was nothing. However, one of the men - Lem Lemoncloak, as book readers know him - is nowhere to be found.

By the time the Hound tracks Lem down, he's sad to see Thoros and Beric have already caught him and two other participants in the slaughter. Apparently, the Brotherhood didn't condone the slaying at the Sept, an act they determined to be punishable by death. Beric and the Hound come to an agreement that the Hound can hang the men himself, which isn't as satisfying as an axe murder, but it gets the job done none the less. Beric then begs the Hound to join the Brotherhood, and it appears as though he's actually considering the offer.

Meereen: Poor Tyrion (Peter Dinklage). He's basically friendless in Meereen now that Varys has left to secure an alliance for Dany (Emilia Clarke) in Westeros. (Since nobody seems to hate the Lannisters quite as much as Ellaria and the Sand Snakes, we'd bet good money Varys is heading to Dorne.) But Tyrion refuses to let this get him down and forces Grey Worm and Missandei into drinking wine and joking around with him. Unfortunately, their charming little party is cut short when the slavers' fleet arrives and attacks the city. Things go from zero to one hundred very quickly, but fortunately for our heroes, Daenerys pop up out of nowhere to save their sorry butts.

King's Landing: Following a successful standoff with the Faith Militant, Cersei is easily defeated by her uncle Kevan, who exiles her to the gallery when she shows up to witness one of Tommen's (Dean-Charles Chapman) royal announcements. But it's probably for the best that Cersei was in the back of the crowd, since Tommen called an audience to declare Cersei and Loras' trial date and - more importantly - the fact that trial-by-combat is now outlawed. (Sorry #Cleganebowl truthers.)

Riverrun: Rather than go directly to the Blackfish, Brienne (Gwendoline Christie) and Pod stop and say hi to Jaime (Nikloaj Coster-Waldau) and Bronn first. This is great for so many reasons, the first of which being we get a scene of Bronn and Pod discussing how much Jaime and Brienne want to f--- each other - something which makes poor Pod hilariously uncomfortable.

But moving on to Brienne and Jaime, who have been apart far too long. Brienne begins by offering Jaime a pretty sweet deal: Give her the opportunity to convince the Blackfish to abandon Riverrun in exchange for Jaime allowing them to lead the Tully army north. Jaime gives Brienne his word that she has until nightfall to convince the Blackfish, and Brienne gives him her word that if he attacks, she will be compelled to fight him.

Unfortunately, the Blackfish has no intention of abandoning Riverrun. And can you blame him? Sansa wants the Blackfish's army to reclaim her family home, so why should she expect the Blackfish to give up his? Not that the Blackfish's rational reasoning does anything to quell Brienne's guilt at failing Sansa.

Jaime's morale isn't fairing much better when he goes to talk to Edmure (Tobias Menzies), who throws Jaime's past and reputation in his face. "How do you tell yourself that you're decent after everything that you've done?" Edmure wonders. But rather than the noble Jaime we've seen in recent seasons, we get the Season 1 Jaime, who declares his willingness to kill anyone - even Edmure's infant child - to get back to Cersei.

So Jaime and Edmure strike their own deal. Jaime lets Edmure go take command of Riverrun, but then Edmure merely hands the castle back over to Jaime. Proving he's kind of the worst, Edmure then orders his men to capture his uncle with the intention of handing him over to the Freys. But before the Blackfish is cornered and killed (offscreen, mind you), he manages to get Brienne and Pod away safely. From the top of Riverrun, Jaime watches the pair row away and he and Brienne share such a look that we temporarily forget all about Tarthbane.
