Re: "Yeah, it's going to be fun"- The Black Widow/Scarlett Johansson Thread
While I'd love to see them explore BW & Hawkeye in Budapest, I think that would be best explored as an 'event' episode on TV.
My personal preference is that any of the feature film projects should continue to push the narrative and overall timelime forward - CA:TFA should be the only 'out of continuity' film Marvel makes IMO. Especially since the films going forward are dealing with the fallout from Avengers, I feel that it's in the studio's best interest to continue with that line of thinking.
The TV show is a great place to provide these flashbacks that can build upon the characters we've seen in the films. With the buzz surrounding the Agent Carter One-Shot, Agents of SHIELD would be a neat way to show occasional flashback episodes.
