I believe that the DLC characters from the Indiegogo campaign and the Season Pass characters should also say their voice lines while on the player 2 side. The reason for that is because the characters in the base roster said their voice lines while on the player two side while Skullgirl Umbrella said hers on the player two side while Marie is on the player one side, so I think that the DLC characters from the Indiegogo campaign and the Season Pass characters should also say their voice lines on the player two side. If you catch my drift, it can make the game even more lively.
