Continuity mistake: At the end of the episode, when Bender and the Countess Delaroca are hanging on to the escape pod, the diamond on the diamond bracelet the Countess was hanging onto changes position between shots.
Continuity mistake: In the intro, before the main titles, the Professor informs the crew that he's booked them on the maiden voyage of the Titanic. When Leela says "Looks nice," at the beginning of the "scary" Titanic montage, the right side of her shirt is undamaged. During the middle of the "scary" Titanic montage, it suddenly becomes torn.
Continuity mistake: The food cart dissapears once LaBarbara stops playing it. (00:17:20)
Continuity mistake: The spaceship Titanic, when seen from space and at the dock, has a yellow trim around it. However, when Bender and the Countess are parodying the scene from the 1997 film Titanic, the trim is white.
Continuity mistake: During the Titanic's naming ceremony, Zapp stands next to the ship, with the word "Titanic" in shot, just above the grey part of the hull, very low down on the ship. However, during the rest of the episode, the word "Titanic" is located further up, just below the white trim.
Continuity mistake: Zoidberg holds the airlock open with his claw while lying on the floor. As the door lifts up and opens Zoidberg is stood up and first through the door.
Answer: Yes Leela knew from early on that Fry had feelings for her. They were pretending to be a couple in 'A Flight to Remember' from season 1 and Fry tried to get on dates with Leela ever since. She just didn't show signs of the feelings maybe being mutual before some of the later episodes.
