I just recently watched an episode of the animated series (which is accepted to be canon) where Spock uses the Time Guardian to go back in time and save his younger self to correct a change to the time line. But he doesn't put the time line back completely when he fails to save his pet saber-tooth-bear-thing. They mention that this may cause time ripples, but we never know what they might be.

Pfffft. Did he pencil that in?

Yeah, if that is a proper porn stache then porn staches have lost their mojo.

Yeah, sorry not a porn stache. Oh, except maybe a Mexican porn stache, and that's where he was headed ... so kinda makes sense.

Maybe it's for a part.

Eeeww, used car salesman mustache. Boo.

I think it's obvious. The next Trek is a remake of Mirror Mirror and that's his evil Spock look.

Nailed it.

Apropos of nothing, I've always thought that instead of that weak theme music they used on Voyager they should have revived the captain's voice over, but made it "These are the enterprises of the Star Ship Voyager".

But then, maybe they did and Janeway just sounded lame doing it.
