A Big Piece of Garbage - S1-E8
Continuity mistake: When Bender is ordering from the wine list, the waiter's notepad changes colour from yellow to white. (00:02:40)
Continuity mistake: When the liquid person is telling Fry about the coming coronation, the background behind him changes i.e. during the closeup of his face the wall should be a window section. (00:10:45)
Continuity mistake: When Bender's cans first drop out of his jacket onto the floor, the number of extra items on the floor increases when the security cameras are looking down on him. (00:04:55)
I, Roommate - S1-E3
Continuity mistake: When Bender sits beside Fry on the couch, Bender's sitting at the end with his arm on the rest. When Fry says 'Leela, we're trying to watch TV' Bender's moved to the middle of the couch. The garbage next to Fry and the contents on the table also change in this scene. (00:03:35)
Love's Labors Lost in Space - S1-E4
Continuity mistake: We can see that the door of the cargo area is nearly on the ground. How come Fry can then run out of the same door and then fall out of the door near the top of the ship? (00:17:00)
Continuity mistake: Fry reads his speech from the back of his arm, but the writing disappears afterwards e.g. when the emperor appears in his stomach. (00:14:05)
I, Roommate - S1-E3
Continuity mistake: When Bender and Fry are at the bar, Bender has four glasses and a cigar in front of him on the table when he says, "Cheer up, meat bag. You barely touched your amoeba." When it cuts, from behind Bender the cigar is missing. (00:04:35)
Continuity mistake: When Fry is trapped in the Cryo-Tube we see the buildings being destroyed and rebuilt, the final city is rebuilt, Fry unfreezes and steps out of the Cryo-Tube and the buildings out the window are completely different. (00:02:30)
Continuity mistake: When Fry is being emperor and Leela is questioning his actions, there is a water being with a yellow mouth cover. Later, there is a pink mouth cover on that being.
Love's Labors Lost in Space - S1-E4
Continuity mistake: In the scene around the table, Leela is holding a lilac coloured cup. This changes to a red coloured cup later in the scene. (00:04:05 - 00:05:10)
I, Roommate - S1-E3
Continuity mistake: When the TV first loses transmission and fills with static Fry taps it and it tunes back in, he then does his Fonz impression facing the sofa, it then cuts and he's facing the TV. (00:12:45)
I, Roommate - S1-E3
Continuity mistake: When Fry uses the ship engines to dry his hair, the Planet Express ship has rotated 90 degrees from the previous shots. (00:01:45)
Continuity mistake: In the scenes with the robot elders, the colour of the Elder's eyes change frequently between shots.
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.
