Well we were expecting to see the Rogues on 'Flash' eventually and one key member might be joining them soon...but first he'll be seen on 'Arrow.' Nick Tarabay (Star Trek Into Darkness, Spartacus) will portray Digger Harkness aka Captain Boomerang. He'll make his debut in the seventh episode of the season and then continue into the eighth episode which we know will be the crossover event episode with 'The Flash.'
