With speculation growing, Coy Stewart - who plays Flint in Agents of S.H.I.E.L.D. - has suggested life on Earth may be too much for Flint.

Agents of S.H.I.E.L.D. Season 5 has taken a science-fiction twist, stranding Coulson and his team in a dark, dystopian future. One of their most fascinating allies has been Flint, an Inhuman with the power of "geokinesis." He can literally manipulate rocks at will.

The character has proved to be tremendously popular. Fans are eager to see Flint become a permanent member of the cast. In an exclusive interview with Screen Rant, actor Coy Stewart discussed what he imagined Flint's life on Earth would be like.

"Life on Earth is a lot to take in," Stewart noted. "There's a lot more factors that he'd have to think about that he doesn't have to in the future." He's certainly got a point; the future timeline Flint lives in is a harsh and unpleasant world, but it's also a simpler one. Kree are at the top of the pile, humans have to struggle to make ends meet. The only aim in life is to survive. In contrast, were Flint to travel back to the present-day he'd find himself dealing with all the complexities of the real world.

It's also worth noting the experience would be challenging in another sense. Flint has grown up in a claustrophobic bunker, and that's simply what he is used to. The prospect of living on the surface of a planet would no doubt be an exciting one. At the same time, it would also be strange and disturbing. Just the fact there's no limit to the horizon would be a challenge for Flint, while the sheer number of people living on the planet would also feel intimidating.

Of course, the reality is that Flint wouldn't have to deal with this eventuality alone. Stewart admitted that he's seen the fan-theories suggesting he could travel back to the past. What's more, he's been particularly interested in the idea given the relationship between Flint, Mack, and Yo-Yo. Those two could so easily become surrogate parent-figures for the young Inhuman, helping him find his way in the world. As Season 4 revealed, Mack's deepest desire is to be a father, and Flint could fulfill that.

"I think [Flint's future] is up in the air," Stewart noted. Although he joined the show five seasons in, the actor swiftly found himself "part of the family" in Agents of S.H.I.E.L.D.. "They're an incredible cast," he observed, "and they definitely made me feel at home." The simple truth is that Stewart really doesn't want this experience to end - and neither do the fans.
