This. Tuvok mostly remains an underused character, but he gets his moments. "Meld" in season 2 being the most intense and my favourite one. In fact the #2 on my list of best VOY episodes.
Curious, what was your favourite?
I relish the scene in 'Meld' (and I admit to re-quoting it before)
JANEWAY: Tuvok, do you know where you are?
TUVOK: (laughs) Of course I know where I am, Captain. I'm just not sure I know who I am.
EMH: Try to relax. The treatment still has about three minutes to go.
TUVOK: Oh, it must be working, because I feel very strong. Very powerful. Quite euphoric. This must be how my ancestors felt. Doctor, would you consider allowing me to remain this way for a while? It would be a valuable opportunity for me to study primal Vulcan behaviour.
EMH: Sorry, I'm not prepared to do that. The course of treatment is very specific.
TUVOK: You are not invulnerable, hologram. A few well chosen commands to the computer and you will cease to exist.
(Tuvok throws a wheelchair at the forcefield.)
KES: Two minutes, thirty seconds left.
TUVOK: You look shocked, Captain. You must be asking yourself, what if this doesn't work? What do we do then? I have an idea. I'll just stay in my quarters for the rest of the trip. I'll just relax and read, eat the ship's food, use the ship's energy, all in the comforts of my own room. Why, even Mister Suder and I could get together for a few hands of Cardassian pinochle once or twice a week. That is how we treat violent offenders on this ship, isn't it?
