Takar: You're not behaving very rationally.
Janeway: That's what you were trying to accomplish, wasn't it? Hmm? Pumping up my dopamine levels to push me to the edge? Keeping me awake for four days straight with the constant pain of your devices drilling into my skull? Well, this is the culmination of your work, and guess what? You're going to be right here to collect the final data.
Janeway: Go ahead. Without us, you won't be able to prevent this ship from being torn apart by the pulsars, and even with my crew working together, I'd say the odds of us getting through this are, what, one in ten?
Tuvok: One in twenty at best, Captain.
Janeway: I'm willing to take that chance. Are you?
Janeway: I never realized you thought of me as reckless, Tuvok.
