They have to have the name conversation eventually. They come up with all sorts of ideas for girls names, like Martha and Susan and Sarah Jane. They consider Jackie, but decide that it would be far too confusing with two Jackie Tyler's. The name he likes the most is Donna because in a way she's kind of his twin sister, the human part of his DNA. He knows what's going to happen to her, and he hates it terribly, but he can honour her this way. For a middle name he doesn't really mind all that much, and Rose suggests Jennifer as a testament to Jenny.
He thinks he likes it.
As far as boys names are concerned, Rose wants either Jack or Mickey in the name, for the two people she misses the most. Chris's only protestations are that it might encourage their child to behave like their namesake, and that's something he doesn't want at all, never mind if they use Jack.
But Rose is insistent.
And Chris doesn't mind all that much.
