"I grew up in Riverrun, an' I know the place inside an' out," said Lois. "There's an underground passage that starts in a hole by the riverbank and comes out right in the middle of the castle. We can sneak in through there."

"And then we can whack those weaselly Freys, and rescue Grunkle Stan!" Mabel cried in ecstasy.

Lois looked at her. "I dunno if you an' your brother should come with us. You're just kids. You could get hurt."

"Hey, we've fought the White Walkers!" Mabel said. "The Freys will be a breeze compared to them."

"The White Walkers?" Lois said. "I thought they were just a myth. When did ya fight them?"

"When we went up beyond the Wall with Stewie," said Dipper.

"North of the Wall? What were ya doin' up there?"

"It's a long story," Mabel said. "Anyway, you don't need to worry too much about us. We can handle ourselves just fine."

"All right," said Lois. "I hope ya know what you're gettin' into."

When it began to grow dark that night, Lois led Dipper, Mabel, Hayley, Jeff, Roger, the Hound, and many members of the BWB to the Red Fork, the river that ran by Riverrun. They were well out of sight of the actual castle, so there were no Frey soldiers around.

After leading them along the river for a little way, Lois suddenly swung herself over the edge into a hole in the riverbank, a little above the water. Dipper and Mabel got down on their knees and peered over the ledge to see where she had gone.

Lois's head poked out of the hole. "I'm down here!"

Mabel swung herself successfully into the hole, just as Lois had done. She found herself standing in a huge tunnel. "This is so cool!" she exclaimed. "Come on, Dipper!"

Dipper entered the tunnel after his sister. "Whoa," was all he could say.

Hayley came next. "Wow, I bet I could walk by this spot a hundred times and never know this was here!"

"No one outside of my family has known about it until now," Lois said proudly.

One by one, all the others entered the passage. Then Lois began to lead the way down the tunnel. It was surprisingly wide, and tall enough so that they could walk upright without bonking their heads.

The Freys had captured and occupied Riverrun by this point. Lame Lothar and Walder Rivers were in charge of the garrison. Right now, they and their men were having a feast and getting pretty drunk.

Lothar stood up to make a speech, wine sloshing from the glass he held in his hand. "I should like to shay a few wordsh about our kind hosht, Shtanford Pinesh."

Grunkle Stan was in chains, lying in the corner of the room. "Actually, my name's Stanley," he said. "Stanford is my brother."

"We all know Shtan," Lothar slurred. "Good Shtan, modesht Shtan, honesht Shtan!" There were shrieks of merriment from the others.

On the floor, Stan was grinding his teeth. "If only I could get at ya, I'd teach you a lesson!"

"But you can't get at ush, can you?" Walder Rivers gloated. "You're tied up!"

The passage now began to slope upwards. Lois and them could hear noises coming from above, feet stamping, glasses clinking, and fists pounding on the table.

"We must be under Riverrun now," said Hayley.

"They sound like they're havin' quite a time," said Lois. "Come on!"

They hurried along the passage until it came to a full stop, and they found themselves standing under a trapdoor.

Lois put her shoulder to the door and heaved it up. She pulled herself up through the hole in the floor and emerged in a pantry, right outside the room where her enemies were banqueting. All that separated her from them was a door.

Mabel and Dipper came up through the trapdoor and stood beside her. "Let's kick some Frey butt," Mabel said.

In the dining room, the Freys were singing "The Rains of Castamere" when the pantry door burst wide open to reveal Lois standing in the doorway.

The room immediately fell silent. Walder Rivers jumped to his feet. "You're dead!" he blurted. "I killed you!"

"Well, ya shoulda made a better job of it," Lois sneered. She ran at Walder and sent him crashing out the window with a flying kick as her comrades came pouring through the door behind her.

The Frey forces were completely taken by surprise. They had been drinking, and most of them didn't have weapons at hand. The sight of Lois back from the dead put quite a scare into them. They thought she was a wight!

So, there ended up being not much of a battle at all. Only a few stayed to fight. The rest bolted with squeals of terror and dismay, trampling each other to get out of the room.

When it was all over, a dozen Frey soldiers lay dead on the floor. The rest of them had fled the castle. "Freys always were cowards," Lois said in disgust.

Dipper and Mabel ran over to Stan. "Grunkle Stan?" Dipper asked anxiously. "Are you all right?"

Stan was shocked. "Dipper? Mabel? I thought you guys were dead."

"Nope," said Mabel. "We're alive and well."

"An' so am I," Lois added, walking over to them. "Let's get you outta those chains."

"Wow, what's next?" said Stan. "Are we gonna find out that King Robert didn't really die either?"

"Or maybe one of the Targaryens is still alive and hiding somewhere!" Mabel joked. "Anything's possible!"

"Where's Pam?" Lois asked Stan. "Is she all right?"

"They've got her down in the dungeon," said Stan.

Lois turned to Hayley. "Come on. Let's go see if we can find her."

It turned out that Pam was being kept in the very same cell where Jaime Lannister had been imprisoned. When she saw Lois, she raised her head weakly. "Lady Griffin?"

"It's gonna be all right now, Pam," said Lois. "We've retaken Riverrun. You're safe now."

"Great," said Pam. "I've got some good news for you, too. Soon, you're going to be a grandmother."

Soon, the feast had resumed, but now it was Lois and her friends doing the feasting. "Give us a song on your lute, Tom!" someone called.

Tom Sevenstrings tuned up his instrument and began to play and sing. It was a song that had become popular with the smallfolk of Westeros following Joffrey's ascension to the throne.

"Oh, the world will sing of an Andal king a thousand years from now,

But not because he passed some laws or had a lofty brow.

Incredible as he is inept, whenever the history books are kept,

They'll call him the phony king of Westeros!

While he taxes us to pieces, and robs us of our bread,

Every day he shits his pants and every night he shits his bed.

And he throws an angry tantrum when he cannot have his way.

He calls for mum and sucks his thumb and doesn't wanna play.

The snivellin', grovellin',

Measely, weaselly,

Blibberin', blabberin',

Jibberin', jabberin',

Joffrey, the phony king of Westeros!"

When Tom was finished, everyone cheered.

Just then, Pam collapsed and slumped forward onto the table. "I think my water's breaking!" she gasped.
