Neville did not recognize the name Matomorvool, but he suspected that Jane did. She wouldn't have gotten so upset when she heard that name for no reason.
Shortly after Professor Dumbledore's brought them back, Neville turned to Jane, gently holding her hands. "Look, Jane, I love you and I really don't care if you're related to a bunch of creeps. It does not matter."
Jane smiled, wide. "I love you too."
Neville was glad she was able to speak already. "Um… do you have an ancestor named Matomorvool.
"Matthew Morvool Clements."
"That's probably close enough," Professor Dumbledore said. "Someone could have thought Mat was short of Matthew. Do you know if he was adopted?"
"I don't know. Maybe."
"Don't be ashamed of your ancestor. You're not even a Slytherin. Also, I have something very important to tell you, but first I was like to point out that our choices show who we truly, far more than our abilities. More importantly, it matters not what someone is born, but who they grow to be. Anyway, not only was Voldemort a parselmouth, he was Matomorvool Riddle."
Jane cringed.
Neville looked at Professor Dumbledore. "Why did you tell her that?"
"She had to find out sooner or later."
Neville paused and turned back to Jane. "I don't even care about that. I love you."
Jane threw her arms around him.
