The Return of Hydro-Man: Part 1 - S5-E7
Other mistake: When Spider-Man catches up to Mary Jane and Hydro-Man at the foundry, he webs up Hydro-Man's left wrist. When the shot changes to Spider-Man landing, he is not holding onto the web-line. When the shot changes back to Hydro-Man, his arm his pulled with the web-line remaining taut, even though Spider-Man is not holding the web. If Hydro-Man was moving his arm on his own, then the web-line would be slack.

Other mistake: When Spider-Man breaks the chain off the steering wheel of the boat, several of the links on the back loop of the chain break off, which would be impossible since he broke the chain at the front.
Chosen answer: Felicia and Peter's friendship in this series was depicted as being on-again-off-again. At this point in the series they may have been on good terms. Plus Felicia is a wealthy socialite and Peter and Mary Jane's wedding was a big event due to Wilson Fisk paying for all of it.
