Fans have speculated that this specific type of facial hair on a Vulcan is a reference to mirror universe Spock's similar goatee, but Mirror Tuvok had no such goatee.

I never speculated this, and I'm sure others haven't either. While I obviously see the similarities, I don't see this as established fact to support the observations of "some". --Alan del Beccio 19:39, 23 January 2007 (UTC)

Not only did Mirror Tuvok not have a goatee, but it has been shown that Vulcans in the primary universe did indeed have facial hair. --OuroborosCobra talk 19:41, 23 January 2007 (UTC)
