Star Trek: 10 Things You Didn't Know About Tuvok
6. A Wise Old Vulcan Here To Guide The Hotheaded Klingon
As fans of Star Trek: Voyager will know, Tuvok and Janeway have a relationship that pre-dates the mission to the Badlands, though this was not the initial focus of the character. According to the series bible, Tuvok - described as much older than he ended up becoming - was planned to become a mentor to B'Elanna Torres.
This version of Tuvok was going to be around 160 years old, a widower, and the father of four children, three of whom were in Starfleet. Though he would have a strong relationship with Janeway, his paternal - or grandfatherly - presence would serve as a source of comfort for Torres.
Though some aspects of this version changed, the bible notes that:
His calm, logical demeanour is comforting to her - and reassuring that one's volatile instincts can be contained.
There are examples of Tuvok and Torres exploring her temper through the series - Barge Of The Dead being one such example - but this seems to have been adapted for another Tuvok-centric story.
