Quote Axl Rose: If Dylan were Nikki and Paul Williams' son then that would make sense when you think about it, Dylan then he would be Heather's half-brother and Ricky's half-brother too but mostly Paul would have a second chance at being a father and Nikki would have another son, Nick would have a brother and Victoria would have a brother too
Nick and Dylan already being rivals because of Avery
Exactly, and Paul would love to learn he has a son with Nikki. He was devastated after Ricky died and wants to make amends. This is his second chance.
