• Suicidal Overconfidence: Bitsy Brandenham, the central antagonist of Central Park, sets up a meeting with the Kingpin after her deal to buy Central Park goes south. It goes about as well as you’d expect.

• Superhero RPF is mainly a Ms Marvel / Loki: Agent of Asgard crossover (had some cameos from other Marvel titles like the Young Avengers).
