Yes I love when you bring Aykira back into the mix. So you have punted the problem of Clark's revival out to Part 4, I can't wait to see how you handle that. An aside, does Iggy's memory wipe mean anything gained by his observation of Clark's regeneration will have been lost or does Lois have possession of his files along with the Kryptonite? Despite how he handled communications or lack thereof with the family he had a good idea to see how Kryptonian DNA re-wrote itself.
