In this episode, Spidey is contact by a talent scout that offers different jobs to him. This time, Peter gives in and actually uses his powers to get some money for Aunt May - although it's nothing illegal. We learn that the talent scout actually works for the Kingpin who orchestrates everything from the shadows to hurt Spider-Man's reputation (as if that would be necessary with Jameson and the Bugle around).
This is the second episode that features the Kingpin. It's great that they use him as a recurring villain but he falls a littlie flat after the global threat of Doctor Doom and maybe they would have benefitted from a little build-up as crimeboss (e.g. Some of the former villains could have either worked for him or mention his existence in the criminal underworld). Nevertheless, the Kingpin as a recurring villain works, especially with him working as a coordinating puppet master from the shadows.
A cool detail about this episode is a news report that gives a little insight about the timeline of the series: It says Spider-Man is around for ten years and his feats besting the Green Goblin, Doctor Doom and the Lizard are brought up. It's a great detail that gives you the sense of an existing world within the series and shows that the creators didn't just work from episode to episode.
