The title is a reference to the song of the same name by the Japanese electronic group Date of Birth.
Eureka begins to understand the importance of family and begins to ponder about having a child the way Talho and Holland are.
Renton begins wondering about what being a parent is like. Unfortunately, when he ponders procreation, Moondoggie and Matthiew spot him inspecting a magazine about sex. Making things weirder.
Misha confirms that Eureka is capable of bearing children just like a human. So she and Renton can have a child in the future that is truly their own.
