SPOILERS for Agents of S.H.I.E.L.D.'s latest episode, 'Past Life', ahead.

Agents of S.H.I.E.L.D. star Coy Stewart believes his character, Flint, could potentially rebuild the Earth.

Season 5 of Agents of S.H.I.E.L.D. has seen Coulson and his team stranded in a horrific dystopian timeline. They discovered a shattered Earth, apparently destroyed when Quake's powers went out of control. The last survivors of humanity live inside the Lighthouse, a mysterious bunker that provides a home for a harsh, dystopian society ruled by the Kree.

Matters came to a head in 'Past Life,' the last episode to air before Agents of S.H.I.E.L.D. goes on a brief hiatus. The Kree have finally been defeated, and the S.H.I.E.L.D. agents have (hopefully) made their way back to the past. It's all thanks to the heroism of the Inhuman known as Flint. He has the power of geokinesis, and used this ability to toss rocks like lethal weapons, and to trigger the Monolith that sent S.H.I.E.L.D. home. But could Flint achieve even more? Incredibly, Coy Stewart actually believes his character could even restore the Earth. In an exclusive interview with Screen Rant, he explained:

"You know what, you never know. I think that one interesting thing is that we have to think about a character like Daisy, like Quake, who when she started out, she wasn't able to do at first what she's able to do now. So, I think the possibilities are endless, honestly, with Flint. I mean, even in this episode we get to see kind of the magnitude of what he can do, and this is just on a small-scale, so I will never opt out to that being an option, for sure."

It sounds far-fetched, but the reality is that Flint is actually still pretty new to his powers. "I think it's pretty badass for this young man who just received his powers to be using them so well, so early," Stewart observed. It's also true to the comics, where Flint is a relatively new character. He was created by Charles Soule, and originally used his powers just to toss rocks - just as he did shortly after undergoing Terrigenesis in Agents of S.H.I.E.L.D. Recent comics have seen Flint topple entire mountains. In fact, in one staggering arc he actually used his power to move Pluto as a weapon. Stewart admitted that, while he didn't know Flint was an Inhuman when he auditioned for the role, he's now up-to-speed on the character; he was even aware of the Pluto feat.

As Stewart notes, Agents of S.H.I.E.L.D. has previously shown Inhumans have a learning curve with their abilities. When Daisy's powers first manifested, they were raw and unpredictable; she caused objects around her to vibrate dangerously. She's learned to focus that as devastating waves of kinetic force, and over the last few seasons has pulled off some outstanding feats. Now, Daisy is clearly one of the most powerful Inhumans of all - perhaps even able to crack a planet. All these skills weren't accomplished overnight, they took training. As powerful as Flint may be now, what will he be capable of when he's grown and matured?

"Here's your blueprint," Tess noted as she held a globe up before Flint's eager eyes. She, it seems, believes this young man could actually rebuild a planet. Given Terrigenesis tends to have a will, "evolution in advance" as the comics have called it, it's possible he really is the solution to the Earth's problems. Agents of S.H.I.E.L.D.'s latest pod has definitely ended on an optimistic note.
