Not too far away back at the lab that was able to cure Tabitha of her ever growing illness they kept a DNA sample of her.
This was in the care of Doctor Felix McCoy. He was seeing if he could get the growth from her DNA and he could possibly create an army of giant soldiers for protection.
But he was careless for women. He could be easily wooed by a hot woman. And unfortunately for him there was one.
This woman was named Cassandra. She had blond hair and blue eyes. She had a nice body and was average height. She was ale to sneak into the lab to be with Doctor McCoy. But deep down she only wanted his research.
He had accidentally told her about the DNA and she wanted it for herself so that she could gain Tabitha's powers. He had made it into a formula that was ready for testing.
A few weeks later we see him researching in his lab. At first he's all alone until Cassandra came in. She closed the door behind her.
"Cassandra please not now," he said.
"Oh but I'm so lonely," replied Cassandra. "I need a little company."
