Lets see, something we would never guess...I've got it! Ruby's father is a scientist and after the death of Summer Rose, he took some genetic material from his love and began to clone her. He then mixed in some of his own DNA and created a daughter, Ruby. He then named her after Summer. It is so obvious!
