Lyanna and Jaime were told to wait in the Solar on the day when Lord Tywin and Tyrion finally arrived. Lyanna's anxiety about the meeting had all but dissipated in recent days. Now it was Jaime who was anxious, He paced the room more worried than Lyanna had ever seen him. Ned and Cat had gone to the gates to meet their guests. They would bring them to the solar for a private meeting but that had been nearly an hour ago, probably one of the longest hours of Jaime's life.
They heard footsteps approaching, Then Ned's voice. "I think you'll find that Winterfell stays plenty warm in the winter even for Southern blood. We have water from the hot springs piped throughout the whole castle."
"So I have heard." Lord Tywin said, not quite sounding impressed. They were just outside the door now. Jaime stopped pacing and Lyanna took his hand.
"Lord Tywin, I must tell you that I have other guests waiting for you in my solar." Ned said as he opened the door.
Tywin stepped into the room and stopped short. "So it's true." He said on seeing his son.
Tyrion pushed past his father and went to hug his brother.
"I'll leave you to speak alone." Ned said.
Tywin took a moment to gather himself and then he too gave Jaime a brief but firm hug. Then he turned to Lyanna. "You must be Lyanna Stark. I owe you my son's life and as such am pleased to meet you."
Lyanna smiled and curtsied. "I am pleased to meet you my Lord."
"I can see why my brother was taken with you." Tyrion told Lyanna, "But why you would run off with the likes of him is still a mystery to us. I do hope we'll be allowed to hear the story." Tyrion said, seating himself at the table and pouring a glass of wine.
"Yes, do tell Jaime, how you managed to escape your fate and end up among the Starks." Tywin said taking a seat as well.
It took nearly an hour to tell the tale. Both Tywin and Tyrion interrupted with questions and Jaime and Lyanna did their best to answer them. Then the children were brought in, both Johanna and Jon. Jaime insisted that he planned to raise Lyanna's child as his own and that Jon be counted among the family. Tywin agreed but only because Jon was a Targaryen, a possible key to power and he had no qualms about making his reasons known. The meeting went well enough and after a long while spent getting to know the children, longer than Jaime might have believed his father was capable of, the children were sent off to bed and the Lannister guests were seen to there rooms.
The smile that Lyanna had plastered on her face disappeared the moment her good father and good brother had gone. "What does your father mean by 'key to power?" She asked Jaime.
"I'm not sure. I only know that power is very important to him" Jaime said, running his hands through his hair.
"I'll not allow him to use my son start a war!" Lyanna told him.
"I doubt he'd start a war. The rightful king is my sister's son. What good would it do him to replace a half Lannister king with one that doesn't have any Lannister blood?" Jaime said.
"Maybe you're right." She said, trying to relax herself.
"Of course I am. I'm always right." Jaime said and Lyanna playfully punched him in the arm.
