Quote alanadz: I am not so sure Jack will be the father of Nikki's son.I don't know if the writers care that much about the father. But this is more a story for Dylan and Niktor. If Nikki IS Dylan's mother that ties him to THE Y&R family, the Newmans.
I'm pretty sure you're right. This is probably JFP's way of keeping Steve Burton (Dylan) around. Dylan only stayed in town for Chelsea and "his" baby. It's only a matter of time before the truth about baby Connor comes out and his marriage to Chelsea will end. Making him Nikki's long lost son ties Dylan in with the Newmans and gives him a reason to stay in town (and for Steve to stay on Y&R)
