Chaol was seriously injured, and he was can no longer walk. King Dorian has brought in the best healers to assess him and there is nothing they can do for him. They want him to continue to try but it is unlikely her will be able to walk again.
You are a veteran healer and are brought in to help him daily. You were given quarters beside his in case he needs anything. The first day you meet him, he is in a rotten mood and lets you know he doesn't want or need a babysitter. He goes on a rant for awhile then asks you to leave, which you comply.
Today however you do not plan to bend that easy, you have a job to do and plan to take care of him whether he likes it or not.
You walk in his room only to get a rude greeting, "Get out, I made myself clear yesterday."
