That made Link laugh a little. "Well, good luck with that one," he said. "Not even the old Sheikah technology can pull that off."
He was quiet a moment, studying the two women. Yammo said 'their child,' which was the way it should be, since they were life partners; in normal circumstances, that'd mean his part was done, glad to have you as a friend and a neighbor, but that's it. But Zumi had said she was glad to hear that there wasn't anything between him and Zelda as part of this announcement, which told him there was more to it than just 'thanks for being a genetics donor.'
Well, it was their child, he wasn't going to ask one way or another- that was on them to do. So he smiled. "Congratulations, you two."
