Personally I happen to like Vorik, but I fear you'll find little love for him in this forum. He gets picked on unmercifully around these parts.
I agree though; no one seemed to give a fuck about him other than the doctor and maybe Tuvok. Vorik is kind of treated like a villain even though his actions were beyond his control. I think he deserved a little more compassion than what he got.
I could give two shits about B'elanna and Tom honestly. Fuck or don't but they need to make up their minds.
