Also, I do think it would have been more interesting to proceed with Tuvix from a storytelling point of view. Obviously that doesn’t work great when you have actors contracted for multiple seasons
I was okay with Tuvix being split back apart eventually, but if VOY had fully committed to the serialised nature of its premise I would have loved to have seen Tuvix hang around for, say, 5-10 episodes first. They could still have had Neelix and Tuvok appear in the odd flashback or as holo constructs or something to justify their inclusion in the opening credits. Or, to be even more daring, not have them appear at all and removed Ethan Philips and Tim Russ from the credits for a while, although I don't think this sort of credit manipulation was permitted in the mid-90s. It would have made the impact of killing Tuvix even greater.
They never speak of it again. Probably because Janeway threatened to murder anyone on the ship who brings it up.
And that's what makes her the highly effective officer that she is. :-D
I think that after the season of LDS is done, while we’re waiting Disco season five, I’ll try and do some Non-Canon Connections.
