As they entered the wing where Janet's room was, they heard her talking. It sounded like she was having a conversation with herself. In fact, she was having a conversation with herself, or at least another her. For Aunt Janet had two heads.
"Hey, sis," said both heads in unison. One head looked just like Janet had before, a short, but feminine haircut. The other had hair that spilled down their back.
That must be the 'new' Janet, thought Jon. Or whatever she calls herself.
"Hey, sis," said his mom. "And other sis, I guess."
The head on the left, the one with the long hair, laughed. "Yeah," she said. "I'm new. I still haven't decided on a name yet, but Janet's helping me." They sat up in bed, revealing that their chest had been widened to accommodate the new head. A third breast had been added between the original two to occupy the new space between them. They also had four arms.
"I decided to give my new sister her own set of arms," said Janet. "It just seemed too difficult to try and coordinate our movements if we only had one hand each and not fair if only I could control them. We can both feel what all four hands touch, regardless of whose hand it is, though."

"No," said Janet. "I felt that we'd only get in each other's way if we did that. I control the legs. Sis can feel what comes from them, but can't move them."
"And you're fine with this?" Jon asked his new aunt, increculously.
"Sure," said his new aunt. "I can still feel them, and I get a free ride. Isn't that right, Janet, honey?"
"That's right," said Janet. "I get the control, but I do all the work." She turned to her new sister and said, "So no complaining about sore feet or how your legs are tired, all right?"
"Sure, Janet," said her new sister. "Now, about that name..."
