People honestly portray Tuvok as far too "rolling his eyes, reluctantly going along with Janeway's silly little shenanigans" - he's literally so serious about being right there with her on every decision she makes. Janeway's like "I'm going to stay behind if the ship blows up" and Tuvok's like "I'm staying with you." Janeway's like "I'm going to deliver every member of the Equinox crew into the jaws of death via an alien revenge massacre" and Tuvok protests a grand total of one time before being fully on the bridge assisting her. He was the only one with her when she made the decision to honor the caretaker's wishes and save the Ocampa, dooming them all. He was willing to get court marshalled in order to fulfill a wish she couldn't grant by her own hand: Get them home [no matter what happens to me] <- wherein 'me' is Tuvok. This was the same wish that spurred him forward when he had to leave her on that planet and everyone left thought him cold for trying to fulfill it without her when in his mind it was akin to a dying wish, the last thing she'd ever express to him: Get them home [no matter what happens to me.] <- wherein 'me' is Janeway. He told Seven that the golden rule to follow is that the captain is "ALWAYS RIGHT" <- (His ACTUAL words) and when Seven asks if the captain should be followed even if someone KNOWS she's wrong he says "Perhaps." This man is perhaps the most ride or die dude in the universe about Janeway. Despite her labeling him her 'moral compass' he is by NO means impartial or unbiased. He'd defend her to his last breath. He canonically makes detailed psychological observations about her and has for years. He accounts for her luck when calculating the success of certain plans. It's implied in 'Twisted' that Janeway typically listens to Tuvok's suggestions and follows them nearly without fail - to the point that he's surprised and obviously irritated when Chakotay doesn't. Despite this they've been inside one another's quarters so infrequently that Tuvok can remember each instance. They call each other "Captain" and "Mr. Tuvok" even though they've known each other for twenty years. There's something wrong with them.
