In-Laws

AU. Rouge wasn't expecting so much to change after adopting a Chao and raising it as her own. But now the Chao has grown and given birth to an egg. The father is not only a Hero Chao, but his owner is none other than Knuckles the Echidna. This inevitably ties the two of them together. Will they be able to set aside their feud for a baby? How hard do they have to try?
