Alongside Kate Bishop, Echo was one of the characters introduced by Hawkeye into the MCU. Played by Alaqua Cox, the character is slated for a self-titled spin-off in the near future. Information on the show has been kept under wraps but a new listing indicates that there are some major MCU appearances waiting to happen in the show. Charlie Cox and Vincent D’Onofrio are two of the names listed on the resume of the show’s costume designer Stacy Caballero.

Those two names shouldn’t come as a surprise given their character’s history in the comics. With the way Wilson Fisk’s stint in Hawkeye abruptly ended at the hands of Maya Lopez, it makes sense to see the character make a return. As for Daredevil, where there’s Wilson Fisk, there’s Matt Murdock.
This isn’t the first time some key information has been accidentally revealed through a personnel’s resume. Avengers: Endgame was infamously listed on the film’s cinematographer’s online resume which fans thought dubious at the time of the leak. Of course, there’s a slim chance this could be conjecture on Caballero’s part but all evidence points otherwise.
