Thirty days after this is posted the ending favored by the greatest number of reviewers becomes part of the Best Enemies universe.

Chapter 1 - Amy's Offer

Shego assumed Amy had called to apologize for missing the twin's eighth birthday. DNAmy offered an explanation for her absence, and then went into a rapturous description of her new job at a Danish university. Half way through the call, however, it took a turn Shego had not expected.

"I told them what I had done; that I had applied Tomohiro Kono's research on two women, and that daughters had been born."

"You didn't tell them our names, did you?" Shego asked sharply.

"No, I didn't. They were curious, but that's for you and Kim. They did, however, encourage me to reproduce the procedure. They want to see it done, it would represent an advance in our knowledge of reproduction."

"They'll let you do that?"

"I think I'm going to like Denmark. I'm going to have more freedom here. They're letting me choose the test subjects. There are couples who would fight for the privilege. I asked you five years ago, do you and Kim want to try for another baby?"

"This is kind of sudden, I don't-"

"You need to decide fairly soon. I'm gathering the equipment and thinking of the team I'll need now. You're pushing thirty-five, Shego. You won't be an ideal candidate for the procedure much longer."

"I can't decide on something like this over the phone. I have to talk with Kim. I… I probably need to talk with the girls."

"When can you get back to me? I told the board of directors I had someone in mind. I want to be able to tell them something by the end of the week."

"Can I get back to you in a couple days?"

"That's fine. Remember, even if you and Kim want to try for another there are no guarantees. You two were incredibly lucky the first time. You might not be that lucky again, but I want to give you the chance."

Supper that evening was a Greek salad. As Kasy dug out bits of purple onion to leave on her napkin and Sheki discarded the cucumber, Shego remarked casually to Kim, "Amy called to today."

"What did she want?"

Shego waited until Kim was taking a drink to answer, "She wanted to know if we wanted another baby." The water came out of Kim's nose in a very satisfying manner.

And the proposition effectively defined family discussion for the rest of the evening.
