What I think went through Jon's head when his friends brought him back to the wall and he decided he wasn't leaving.

I take in a deep breath as I close my eyes, I think of my sisters, my brothers, my father…I am sorry to them, part of me feels guilty about abandoning them to whatever fate, no, not fate, but destiny. We were all destined for something the day we came into this world. The story of our lives won't be a sad one, it will be great one, a legend that will be told for centuries. My father did not live a sad life, he died in a sad way by a corrupt boy, but the life he lived was truly magnificent. If he were here now, he would know this choice was right, the point of living is not to live forever, but to create something that will. We all have our parts to play in this world, whether that is to die, to live, or to do something great, the choice of course, is always ours. This is my place now; I am the watcher on the walls. Even though I cannot help them where they are going, I can help them where I am going. I expect to see them again someday, I hold on to that hope, even if it is a false hope….
