it's interesting that in the epilogue the book switched from calling himself Coriolanus to Snow, he really has left his past behind.
he clearly learnt no lessons from his experience, that would require a level of introspection he is not capable of. i still can't believe he called himself "the best of the best" he is so full of himself.
i like to think lucy grey escaped and made her way north. it is not unreasonable to assume there are still people living outside the districts, america is a big country after all. i am torn on whether the snake was a trap set by her or just coincidence he latched onto with his paranoia. she did warn snakes lived around there last time and as the doctor said, the rain draws them out. it's a good thing he found the guns and returned though, i fear for her safety if they had made it too far out and then he lost his temper
