It's worth noting that Roman was originally meant to be a one off character, but RT liked him enough to keep him around. In fact, the villain of the Volume 1 finale was originally going be Corsac and Fennec before they decided to expand Roman's role. So it's possible that the Albain twins could've been in Roman's place instead. Considering that, Roman wasn't meant to have a huge role in the first place.
