Kevin's Brother From Another Mother (Sequel to A Gotham Christmas)

After Barbara Gordon (Batgirl and former Oracle) and Kevin Beaumont (son of Bruce Wayne and Andrea Beaumont) kissed under the mistletoe on Christmas, the two decided to pursue a relationship. And so far, things are looking good. But when you're the son of Batman, and you're dating Batgirl, it's a miracle if you can live a semblance of a normal life. Kevin's soon going to learn that he's not the only son of Bruce Wayne.
