Of course, we already know that Yelena Belova will feature in the Disney+ Hawkeye series, so it’s possible that Pugh is just looking forward to that project. The “hope” piece of her message, though, seems to imply that she could be referencing something that hasn’t yet been confirmed. It seems like a given that Yelena would serve a more prominent role in any future Black Widow-focused stories, given what we know about the trajectory of Natasha’s storyline. So by that logic, Black Widow 2 would definitely put Yelena back in action.
