Character mistake: At the start, Captain Janeway reveals that she has discovered Tuvok's birthday. Then she says it's not long before he hits the big 3-digits (meaning 100 years old). However, Tuvok was 107 when he infiltrated the Maquis and they've already spent 6 years on Voyager. Even if she didn't discover his birth year and was only guessing. Tuvok would not have replied with "indeed" but pointed out she is wrong.
