Marvel has been tight-lipped when it comes to Avengers 4. Which is not exactly surprising, given that Avengers: Infinity War hasn’t even hit theaters yet. However, that hasn’t stopped rampant fan speculation, which has only been fueled by some leaked set images that appeared to imply the use of time-travel in the film. Will we see Tony Stark, and company travelling back in time to fix some kind of mistake made in Avengers: Infinity War? Talking on MTV’s Happy Sad Confused podcast, director Joe Russo was asked about these leaked photos, and also suggested that fans look back to the MCU’s past, in order to get a hint for the future:

“It’s interesting, because yes, there are photos that always leak, and then there’s lots of conjecture about what those photos mean. Certainly there is a five-minute sequence in Civil War around a piece of technology that was laid in for a very specific reason. So if you go back and look at that film, you may get a hint as to a direction.”

The featured technology Joe Russo is referring to is most likely “Binary Augmented Retro-Framing”, or… B.A.R.F. So, what is B.A.R.F.? It’s a technology that “hijacks the Hippocampus” (according to Tony Stark himself), allowing users to revisit past memories in vivid detail. Stark suggests in Captain America: Civil War that this technology could be used for therapeutic purposes; you’ll know this if you’ve seen Captain America: Civil War, as Tony actually revisits his final moments with his family using the tech.

So, how could this technology be employed in Avengers 4? Let us know your theories in the comments below…
