You imagined the Kazon arc. They're barely there and it wasn't an organized effort to forward their agenda. Martha was in 13 episodes on Voyager. Season 1: 5 episodes, however 4 of those episodes were as a Bajoran extra and no one, not even Berman suspected her destiny till they started writing State of Flux. Season 2: 5 episodes. Season 3: 2 episodes. So really that's 12 appearances out of 68 episodes accounting for the first 3 seasons, Seska was forcing the Kazon to bump heads with Janeway. ... Morn was in 91 episodes.
