Stupidity: The last remaining Xindi, in desperation, attempts to release the virus over the fan, despite the virus not being fully ready. However, it seems the only reason he didn't release the virus at that time was he had to seek cover from Archer and T'Pol shooting at him and to start shooting back at them. However, he had plenty of cover from the rooftop stairwell, which was right next to the fan, and he had enough time to dump out the contents over the fan.
Star Trek: Enterprise (2001)
1 stupidity in season 3
The Catwalk - S2-E12
Continuity mistake: T'Pol says she has never been camping, but she went in "Strange New World."
Captain Archer: Enterprise was designed to be a ship of exploration.
Degra: If we're successful, it will be again.
Trivia: When Travis is in his old room talking with Nora about Enterprise, look on the bookshelf behind Travis. There's a large white book about Chicago gangs of the 1920's. In the original series episode "A Piece of the Action" it is determined that 100 years ago the ship Horizon accidentally left a book about Chicago gangs which influenced the entire culture to mimic the mobster lifestyle.

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.
