According to the popular movie site, Spider-Man: Homecoming actress Tiffany Espensen has been added to the cast of Avengers: Infinity War.
Avengers 4 is currently filming in Atlanta, but why would there be an addition to the IMDB page for Infinity War?
Though Cindy only had a small part in Spider-Man: Homecoming, she could very well show up in Infinity War, possibly to get Spider-Man out of a bind.
Afterwards, she becomes Silk and works undercover with S.H.I.E.L.D. This doesn’t mean that Silk will 100% show up in Avengers: Infinity War, but is definitely a possibility at this point.
