Jon
"Jon," Bran said. "I need to talk to you."
"What is it?"
"The army of the dead. The wall has fallen. They've made it into the Seven Kingdoms. It won't be long until they reach here."
"Very well. I'll have the men begin preparations. Thanks for telling me." Bran nodded.
"There's something else as well. Perhaps it's best if we..." Bran was interrupted.
"Your Grace!" A messenger was running to meet him. "Pardon me for interrupting. There's a lone rider outside the gates. Says he wants to speak to you."
"Do you know who he is?"
"Says he won't reveal his identity unless he sees you." Jon sighed.
"It's not a White Walker, is it?"
"No, Your Grace."
"Very well." The King in the North and eight of his guards mounted thier horses and rode beyond the gate. Jon drew up in front of the mysterious man. "Reveal yourself." Slowly the man lowered his hood. Jon widened his eyes and sighed. "Jaime Lannister."
"Jon Snow," Lannister replied.
"What are you doing here?"
"Perhaps we could speak inside? I might freeze to death if I'm out here much longer."
"Deal with him then bring him to the great hall for an audience." Jon rode back into the castle whilst the guards dealt with Jaime - relieving him of his weapons and searching him.
Jon gathered the necessary people - his siblings, Daenerys, Tyrion, Sam and the rest. He was curious as to why Jaime had come alone instead of with the army they had been promised by Cersei.
Five minutes later, and Jaime Lannister was being lead into the great hall.
Jaime
Now weaponless, Jaime found himself in a room surrounded by enemies. Well, Brienne and Tyrion were there but they seemed to be his only allies in what was otherwise a room of people who could very easily want to kill him.
"Lannister," Snow began. "Why are you in Winterfell? Alone?" Jaime caught eyes with Brienne who wore a slightly puzzled look. "Why are you not with the force your sister promised us?"
"Yes. About that... Cersei seems to have been lying when she offered you her army. When I spoke to her, telling her I intended to ride North anyway, she called me a traitor and threatened to have me killed."
"That makes the both of us then," Tyrion laughed. Jaime snorted. "Of course we shouldn't have trusted Cersei," Tyrion continued. "I know my sister too well."
"So," Jon brought Jaime's attention back to him. "You are here to pledge your services?"
"I am."
"But isn't that just convenient?"
"What do you mean by that?"
"You ride north after arguing with your sister. For all we know you could have made a plan and you're here for a different reason. How do we know you are no longer allied to Cersei? How can we trust you?"
"Because I made a vow and I'm willing to honour it."
"We all know you don't keep vows you swore." For the first time Daenerys Targaryen spoke. "My father was the victim of that."
"That was a different situation," Jaime drawled, rolling his eyes. Aerys. Again. Jaime's eyes raked over the two Stark sisters. He raised his eyes to Brienne who nodded slightly. "There's a vow I kept."
"Which was?" Snow asked.
"I promised Lady Catelyn Stark I would get her two girls back to safety. And I got Brienne's help with that. And guess what? They're both back."
"Jaime took that vow seriously," Brienne cut in. Jaime nodded his appreciation in her help.
"I made my own way back," Arya said.
"And who's protecting you now? Who's your sworn shield now?" Jaime asked her.
"Brienne."
"And it was I who enabled her to do so." Then his eyes landed on the Stark boy. Brandon. And he felt a stab of guilt. This was the boy he had pushed out of the window. He hoped the boy would keep quiet. Unfortunately, he had no such luck.
"It was you," Bran said. "I remembered it. I saw it. It was you."
"What was him, Bran?" Jon asked.
"That's how I lost my legs. He pushed me out a window. You were with Cersei." Just like that, the tension in the room became even more palpable than before. He was aware of steel being drawn around him. Arya Stark's face turned to stone, and her dagger was unsheathed. Tyrion stood there, mouth open. Jaime looked at Brienne, his face going red with shame.
"Brandon, I'm so sorry. I mean that. If I could take it all back..."
"But you can't."
"Is this true, Bran?" Jon asked and his brother nodded in reply. Next thing Jaime knew, there was a sword at his throat. Arya Stark was on the other end.
"What's to stop me killing you right now?"
"Don't be hasty, Arya," Jon said. "For now, confine Jaime Lannister to a cell until we decide what to do with him." Jaime was surrounded by a troupe of guards and removed from the room.
