"Is it supposed to be like that?" the man asked, pointing to his leg.
"Normally, no. It has been known to happen in very rare cases though."
"Is there anything you can do?"
"We can remove the leg, but if we regrow it, the DNA strands that we used to promote regeneration will just reassert themselves." The doctor frowned. "I'm sorry, but once it goes wrong..."
"So I can either stay like this or lose my leg again?"
"I'm afraid so."
"I suppose I can get used to it," the man said, running his hand across the smooth, green scales.
