Felicity Jones starred in the second film as Harry's secretary, Felicia. While this might've seemed like a throwaway role, her character was actually Felicia Hardy, who would eventually become the Black Cat. In the comics, she was a cat burglar who ended up having an on-and-off relationship with Spider-Man. This character's appearance on the big screen is long overdue, and it's a shame she never got to don her masked personality. Hopefully, audiences will get to see Jones again as the Black Cat as the multiverse expands in the MCU.
