The way the Fast and Furious has evolved recently would make it reasonably easy for Owen Shaw to return.
After all, the franchise loves to slowly expand the roles of specific cast members (just ask The Rock), so ramping up Owen Shaw to an anti-hero seems in-line with the series’ history.
While his arc could conclude with his assistance in that mission during the climax of The Fate of the Furious, there also seems to be just as easy of a pathway to making him a more prominent member in the franchise is it goes forward.
Seemingly placed on a redemptive arc alongside his brother when they boarded Cipher’s plane to save Dom’s son, Owen no longer stands as the mustache-twirling bad guy that fans were introduced to during the events of Fast and Furious 6.
