Ensign Hoshi Sato: Maybe it's a log. What do you think?
Commander Tucker: Beats me. Could be a laundry list... or instructions on how to conquer the universe?
Trivia: A film reference to Star Trek: First Contact: Archer says something about a group of cybernetic creatures (The Borg), that tried to stop Cochrane from launching his mission into space that was stopped by a group of humanoids, that were also from the future (USS Enterprise NCC 1701-E).
Question: Is the captain's dog still alive?
Answer: Yes. Porthos survives this episode, although many a viewers' sanity and the show's ratings were not so lucky.
