Avengers 4 Reshoots Begin: Set Photos, Returning Characters & More
2. Jeremy Renner Is Back On Set, And He Loves His Hashtags

After sitting out Infinity War, Jeremy Renner's Hawkeye will be back in action for Avengers 4, and the actor recently posted a couple of pictures to his Instagram feed, teasing his return to the film's set as a part of the reshoots.
Some of the hashtags he used in the caption of one of these posts were quite interesting, including "#widow?" - hinting at an Avengers 4 team-up between the OG Budapest crew - and "#A6?", which likely refers to the original six Avengers.
Or, y'know, he could be talking about the Audi.
Renner's return to the set should excite Hawkeye fans for two reasons. One, this could mean the Russo Brothers are adding even more of the character to their story, which would be justified considering his absence in Infinity War.
Alternatively - and if Ruffalo's comments about the reshoots finishing the movie are to be believed - Hawkeye could be an integral part of the film's third act, teaming up with the original Avengers team (#A6) for one final battle together.
Whatever the case, it's looking increasingly likely that Hawkeye has a massive role in Avengers 4, and it'll be interesting to see what he's able to bring to the fight, considering how underpowered he is compared to everybody else.
