Don't forget Tuvok! He was an amazing straight man to the shenanigans of the Voyager crew. I've really been coming to appreciate him more on my current rewatch. I actually get some Tuvok vibes from T'Lyn, just maybe a little lighter and 'carefree' in comparison.

It really is surprising that it took 4 seasons. I wonder if their fear just came from worrying that they might come off too much like every other Trek show with having the 'straight man' type character so focal.
