Jaime opened his eyes to darkness and realized he was still alive, but under rubble. He had no idea how he survived this. Realizing he had been holding on to Cersei, he tried to kick away some of the rubble. He had already been in pain before this so clearly he was in more now. Managing to get out if the rubble, he started moving some more, trying to find his sister. It didn’t help that he could only use the one hand. Finding her, he knew that he had lost her. It was just luck that he had survived this. It would have been too much to ask to have Cersei survive as well. He kissed her before getting to his feet and trying to make his way out.
The wound from his fight with Euron was still bleeding. He needed to get that sorted out before he lost too much blood. Reaching the streets, he glanced around. He never thought he would see the place like this. Jaime was clearly in a state of shock by not only what happened but losing Cersei as well. Leaning against a wall, he closed his eyes as the pain was so bad from the wound. He didn’t even know if he could make it out of here. Pushing himself away from the wall, he carried on walking. He may have lived here for so long but in the state it was in, he was kind of getting lost around here. He needed to find someone. Anyone.
He couldn’t find anyone around. The place was like a ghost town. He had to get away from here. Especially if he was going to get caught by Daenerys’ guards again. He tried to stop the bleeding. He didn’t have the energy to row on the boat Tyrion had mentioned before so he went by horse. He could just about manage that. He needed to get away from here. He decided on Winterfell. He got on the horse and just rode away. His injuries taking a toll on him and his wounds had started bleeding again. Jaime managed to reach Winterfell and at this point, he wasn’t doing well at all and was so close to falling off his horse.
when the guards announced that jaime lannister had returned to winterfell severely injured, it had taken a remarkable amount of self control to tell them to let him through. really, if she were being completely honest, catelyn had wanted to just say “good riddance,” mark him down as another casualty, and leave him there in the snow. but at that point, with so many of the great houses suddenly obsolete and so many sons and brothers (and daughters and sisters) lying in piles of ash by the godswood, it just felt too petty to allow another person to die for the sake of a dead rivalry.
letting jaime bleed out at the gate wouldn’t bring back robb, or ned, or rickon, or talisa, or lysa, or theon.
if nothing else, she couldn’t do that to brienne. (though, after hearing about how he’d ridden off on the poor girl, she was almost tempted to do it for brienne.)
“come, get him off of his horse,“ she told the guards, keeping a cold distance from the man. “bring him inside. he’ll have to be bandaged, and then I’d like to speak with him.“
