Tuvok gave the Captain syphilis in Flashback. This is a fact. It's a living thinking syphilis that makes the carrier think they've accidentally killed some blonde girl until the guilt finally makes their brain explode after a bout of the crazies. If her syphilis flarrrrrrred up, maybe heading towards a terminal guilt spiral, that Kathryn suddenly blamed herself for Seven of Nines death then Janeway wouldn't be responsible for her actions AND SEVEN OF NINE MIGHT NOT HAVE BEEN DEAD! There might have been nothing wrong with the Future she came from and we have no idea how much of it that was bad that we did see... Might have been all an illusional delusional fantasy. Anyone buy this?
