Rick's return in "Secret Invasion" is a relatively quick cameo, but the easygoing way he introduces himself to Nick Fury and delivers some semi-snarky advice to catch some shuteye during the flight makes clear that this isn't just some random guy. With O-T Fagbenle's charisma easily shining through despite his short screen time, this might very well not be the last time we see his character.
In fact, there has been talk that Rick might return in future MCU projects since at least 2022. In an exclusive interview with Looper's sister site, /Film, O-T Fagbenle teased that "Black Widow" might not be the end of the road for his character. "I mean, you know what, with Marvel, I'm never sure how much they can say about stuff, but I'll just say that it wasn't a one-and-done conversation," the actor said.
Rick's profession as a stealthy black market operator who's accustomed to moving people and gear around might indeed come in handy in the current MCU, which features more superheroes than ever but has a lot of them operating on the down-low, without billionaires or government forces to back them up. Perhaps we'll be seeing the character a lot more going forward ... and even if we don't, it's fun to know that Rick Mason is still very much out and about.
