Really fine work! I love the originality of the premise, and the way you play with the many different versions of McKay---not even just over time, but across alternate universes---and how he appears to both himself and others. You add a lot of depth and real loss to McKay's enforced trip to Siberia, too; I choked up about Max right along with him. Come to that, your characterization of McKay is thought-provoking and wonderfully realized in many impressively detailed respects. For instance, I also love his conversation with Jeannie, and how hard Johnny Cash songs hit him in the gut. I like your characterizations in general, in fact, though Rodney's is really the shining example; they all have a sense of real humanity that's utterly believable and effective, and that creates truly powerful emotional dynamics. I would love to see more of what happens next, but the note you end on is satisfying just the same.
