I'm not quite sure how to take that ending. On the one hand, Part 16 was a great wrap up to the conflict that had been building. I definitely did not see that last bit coming, and I'm curious to see what would happen in the PSII era, given that it suggests
Rolf wouldn't be around, or at least not in the traditional sense.
But then you've got the epilogue and
it's all just a dream! The happy ending for everyone is a nice touch and certainly well deserved. I hope it doesn't preclude a possible sequel story, though.
