There's no way to know for sure who Vic is just from 'vic a christmas story'. He could be an ordinary person, perhaps a child or an adult. It depends on the nature of the story.
Her coworkers such as Travis and Ben would be very likely to be featured. Travis might be there to offer his unique brand of support and friendship. Ben, being a doctor, could be involved in taking care of Vic's health during her pregnancy. And of course, her friends from the station like Maya would also be important characters as they support her through this pregnancy journey.
