Three Hundred Big Boys - S5-E11
Continuity mistake: Right before Leela dives into the whale tank, she drops her snorkel and mask, but when the shot pulls back, they've completely disappeared.
Three Hundred Big Boys - S5-E11
Continuity mistake: When Bender is being filmed stealing the cigar, we see the "robocop" showing the footage on his screen. In the wide angle you can see he has the siren on top of his head, then in the next shot it's suddenly not there. Then he actually raises it out of his head in the final angle.
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.
