Ending

You have successfully won Jaime and Prince Tommen over to your cause. With their influence, Kings Landing sends a strong fleet to the Iron Islands where they depose the tyrant Baelon Greyjoy, ensuring safety for the Parre Kingdom for the foreseeable future.

Tommen convinces his mother to spare him any sea expeditions, and instead he returns to Parre with you in the interest of maintaining good relations between the kingdoms. Your life together is happy and your kingdom relatively prosperous. During the war of the seven kings, Jaime is kidnapped by Robb Stark but escapes to Parre to seek refuge.

King Robb takes the Iron Throne and the rest of the Lannisters are killed. Jaime becomes a permanent member of your new King’s guard. As Jaime and Tommen are the only surviving members of the family, the Lannister estates pass on to Tommen, and by marrying him to one of your legitimised daughters, you ensure the wealth of the Lannisters will become a part of the islands wealth. This marriage, political in nature, is untroubled by the relationship between the husband and the father-in-law.
