My thought -about this as a beginning- was that now that he understand that he wants to live, he will finally be able to do so. As to rescuing him -well, he still has a wand, and he is a wizard, is he nor?, and the headmaster of Hogwarts, which is filled with elves and other magical creatures, etc - so saving him from death, not that difficult. And now he wants to live, but he will have to learn how to do so, right? Will he give life as many tries as he gave death? Will he do it alone, will someone help him? Will he see that Albus was right and that he does have the courage needed? Yes, this drabble should be continued with a nice hurt/comfort (long and hopefully Snarry- just 'cause that's the way I like them) story.
