Season 2 of Peacemaker is underway, and fans are seeing something unexpected from the series. What wasn't expected was the introduction of Christopher Smith’s brother, Keith. In the Prime universe, Peacemaker killed Keith when they were kids. We recently had the chance to chat with actor David Denman, who plays Keith in the series, and he took the time to discuss his crucial role in season 2 of Peacemaker. It’s funny, and there’s a lot of action, but there’s a lot of heart.
