The Doctor smiled brightly. "Then I think you'll be pleasantly surprised" he replied with a twinkle in those aged eyes. Eyes that carried more years than his appearance would let on.
"Maybe one day I'll show you" he said, patting the others shoulder. "I know where there are others just like you. Individuals who broke away. Unique, beautiful people!" The kind who would understand his pain, understand what he was going through and they existed in this universe. Cybermen living freely, kept alive with their friends back on Mort. Those altered humans kept the new society safe, kept the new colony hidden from plain sight. But now The Doctor wanted to go back now more than ever to show Kroton that he was never alone. And never would be.
