Plot hole: In 'Oasis,' several times in the episode, specifically when they took Trip captive, the holograms appeared out of nowhere brandishing weapons. The holograms can walk through walls, which we saw, but the guns were real. We saw them hit the deck when Liana deactivated the holograms. So how did they appear with the guns? (00:34:00)
Star Trek: Enterprise (2001)
1 plot hole in season 1 - chronological order
Character mistake: Previous episodes have established this story arc to be occurring in the year 2154. Yet here, when T'Pol records her log, she cites the date as 2152. (00:32:00)
Commander Dolum: You don't want to know my specialty.
Captain Archer: Let me guess... stinking up the room?
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.
