Re: What is "canon?"
So...if there is something stated on one episode that contradicts something in another episode, both are canon even if they are not consistent?
Yes, both are canon. Canon is not about consistency.
Canon is what ever CBS and/or Paramount say it is.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
