When Spider-Man: Homecoming came out last year, we pointed out that virtually everyone in the supporting cast was someone. The big one that caught the eyes of Marvel fans was Tiffany Espensen playing a supporting character named Cindy. Most fans assumed that this was Cindy Moon, aka Silk, a new character to the Spider-Man mythology. It was a fun Easter egg, but no one was really sure if they were planting the seeds for Silk or if it was just there for the fans.
According to Deadline, it wasn't just a fun Easter egg. They are reporting that Sony and Amy Pascal are in early development of a movie based on the character of Cindy Moon, aka Silk. They might have to tweak a few things about the timeline for her character if they were going with her comic book origin, but she's still a fantastic character in her own right.
In the comics, Cindy is a student in Peter Parker's class who also is bitten by a radioactive spider around the same time as Peter. She gains abilities similar to his, though she is able to shoot webs out of her fingertips, possesses an eidetic memory, and has advanced Spider-Sense (known as Silk Sense) far stronger than Peter's. She also has less superhuman strength than him but is faster.
The thing that made Cindy different from the other superheroes like Peter Parker is that she spent years locked in a bunker with only her powers to keep her company. While most superhero origin stories are about the hero getting used to to their powers and adjusting for Cindy it was about getting to used to world. She had to learn how to be in a big city with so much noise, how to interact with people after being away for so long, and other things. Instead of learning how to be a hero Cindy had to learn how to be a human and it made her unique.
It's unclear whether or not this version of Cindy will take place in the same universe as Tom Holland's version of Peter Parker and if Espensen, on top of appearing in Spider-Man: Homecoming was also on the bus in Avengers: Infinity War, would be involved. Sony is not commented right now but now that Silver and Black has been pulled from the slate this would be a good follow-up. Comic-Con International is coming up and Sony could use this to make a splash. Announcing a Silk movie would be a way to do that.
