In "After the Party", Princess Carolyn notices a boy crossing the street that looks just like Vincent. Later, the boy, named Kevin, stops by her apartment and claims to be Vincent's son. While he steps into the bathroom, Vincent shows up at her apartment as well. The two characters are never seen at the same place at the same time.
Kevin seems to be a nice, yet often nervous and awkward child when talking to Princess Carolyn. He even has tantrums like his father.
