I think the show would have been stronger if we'd had all the rebel maquis appearing occasionally in addition to Chell
Well, we did
get Ayala. He even got six lines over the course of seven seasons
There was a black crewman with kinda bulgy eyes that kept popping up from time to time. I can't recall the ep. exactly but it's one where they turn the mess hall into a sickbay & Janeway sits down next to him and comforts him. Does anyone know who I'm talking about? He wears a security/engineering uniform.
On a side note, I'm kinda glad they didn't focus on side characters too much because if you couldn't give enough development to your main members like Tuvok, Neelix, Harry & Chakotay. Then IMO you're stealing screne time from actors that deserved it far more. But that's just a behind the scenes comment. If we didn't have to worry about such things..............then yes. For a ship of only 150, we should have been bumping into Chell or Tal Celest every other episode.
