Jaime:
A guard entered his chambers and surprisingly had a new set of clothes for him.
"You are required to attend the wedding of Queen Cersei and King Euron. Get changed into these. You have ten minutes before we will be back to collect you." Jaime rolled his eyes, causing the guard to punch him in the ribs. "Just get it done." The man left the room.
Jaime knew better than to not do it, but all he wanted to do right now was curl in a ball and block out the rest of the world. But Euron would come in here and get him himself. It would be easier if he submitted. He couldn't believe he was saying that. His father had taught him that a lion shouldn't bow to anyone. He felt useless, pathetic. What was the point now Brienne was gone? The only person he had left was Tyrion and he was many miles away. Hopefully now though, that the White Walkers were gone, the Targaryens were planning an advance on King's Landing.
Jaime did as he was told and put the clothes on. He lay back on the bed and five minutes later, heard the door unlock.
"Kingslayer," he heard the same guard say. "Let's go." Jaime stood up and held out his hand, expecting the man to cuff him. "Not this time. But you behave." The guard propelled Jaime forwards with a hand on his shoulder.
Cersei was getting married again. In some aspect, Jaime wasn't surprised. But there was also a part of him that couldn't believe that Cersei would put herself through that again after what happened with Robert Baratheon. Jaime didn't know why he was caring so much. He should be letting his sister do whatever she wanted, damn the consequences.
Jaime found a deserted corridor and took off, surprising the guard who was rallying more. But he ran into Euron's oncoming troupe. Euron hit him to the ground and twisted his arm. Jaime yelled.
"That was pointless." he thought to himself. His wrists were brought together as he was lifted to his feet.
"You'll pay for that later, brother," Euron hissed. "Take him to Cersei. She'll still want him." Jaime found himself between two guards and he was led to Cersei's quarters. He was taken through where the final preparations were being put to her wedding dress.
Gods, she looks beautiful, he said before cursing at himself, telling himself to snap out of it. Cersei turned to look at him.
"Why is there a mark on his cheek?"
"He tried to run."
"Jaime," she said patronisingly. "You know you're safe and protected here."
"Spare me."
"Now, I'm about to walk down the aisle and get married. You, my dear brother, will escort me down the aisle as our imp of a brother killed our father. Don't protest. You will sit with me up at the high table after and you will enjoy it. After you walk me down to Euron, you will stand with the guards quietly and then you will be escorted to meet us for the banquet after. Let's go."
