Bender Gets Made (a.k.a. Bendfellas) - S2-E17
Continuity mistake: As Bender goes up to the Oilade stand there are four full glasses on the table and a large jar next to them. Bender drinks one of the glasses of oil and puts it down. He picks up another glass leaving two full glasses and one empty one on the table. The following shot there are now three full glasses. After this there are still three full glasses but the glasses have moved to the other side of the stand. The next shot the jar of oil disappears. (00:10:45)

Other mistake: At the end, when Fry, Leela and Bender are sitting at the table, Fry's legs disappear (and the gray blotch beneath him isn't them - it's the table leg; and it's not hiding them either - his knees should be visible behind it). (00:21:35)

Continuity mistake: When the cops spot Bender at the Oilade stand, the letters on the stand become much bigger than in previous shots, and the price disappears.

Other mistake: The strap for Leela's eye-patch on the right side of Leela's head (from her perspective) goes just over her ear. The left side goes above her ponytail. This would prevent the two ends of the strap from meeting.
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.
