I read it, I like it. I think it was a very intriguing and a very inspirational story.
Behind it I saw that, taking what people gave you, you sometimes have to give back, and then take again. Just as Jack took Never-Ending Thirst, Forever-Health, and also Wisdom, he gave Friendship to Nate, and also brought him things, to keep him up to par with the real world. As for the second part of my conclusion, Jack had to help both Sammy and Nate and the beginning of something new. Sammys Career as the "Snake," Of course, by taking Nate's life, but in the end, all was for good and all though Jack had to kill Nate, it was all done for a re-generation phase.
