Loki gives lip service to revenge, but part of the reason he hasn't pursued his initial plans as doggedly as he might have is because he is coming to see that it's a hollow promise. Useful to keep a man wounded unto death from giving up--a fire in the belly to stave off the pain of loss for a little while--but whether vengeance is gained or lost, the initial wounds remain.

He has discovered they must be dealt with. He cannot know yet how Thor has pursued his revenge, but he would be shocked if the thought had not crossed the King's mind. He cannot know how he failed, or the full measure of the guilt he feels, but never doubt I love you still binds him to his brother. It doesn't matter what Thor has or has not done. Not any longer.

"Will you come with me?" He asks, offering a hand. "I have a place no one will interfere with your recovery. I will make sure the others know where you have gone."
