SPOILER WARNING: This article contains major spoilers for "Past Life," the latest episode of Agents of S.H.I.E.L.D.
On Agents of S.H.I.E.L.D., humanity's future looks a lot brighter. In "Past Life," the latest episode, Flint elected to stay in the future so that he could perform one important job: restoring Earth to its rightful state.
In an earlier episode, Flint underwent Terrigenesis, which granted him the power of geokinesis. Using these powers, he can manipulate rocks, minerals and other Earth-like materials. In fact, he was even able to reconstruct the monolith that sent Coulson and his team into the future.
However, when Coulson asked him to come to the past with them, Flint turned him down. "Tell them I had more work to do," Flint said, referring to Mack and Yo-Yo. He then took Kasius' servant by the hand and left for the trawler, which Tess was piloting. They made it just in time, before an explosion destroyed several levels of the Lighthouse -- including the one he had just been on with the S.H.I.E.L.D. agents.
At the very end of the episode, Flint is seen in the trawler with Tess, looking out over what was left of Earth. They discussed Deke's odds of survival (outlook: not great) and shared their hopes that Coulson and his team made it back to the past. "Well, in any case, we got a second chance," Tess said. "Friends from S.H.I.E.L.D. gave us that, yeah?"
Flint offered her a forlorn smile and nodded. She then produced Virgil's little globe, holding it against what remained of Earth. "Clean slate," she affirmed. "Future's up to us now."
"There's a lot that needs fixing," Flint said with a sigh.
"You're right," Tess agreed, handing him the globe. "Here's your blueprint."
Flint took it with a smile, and they looked out over Earth once more as the episode faded to black. This implies that Flint will use his abilities to restore Earth to its proper state, so that humanity can begin to thrive again on a more habitable surface.
If Coulson and his team are successful, Flint may not have to restore the Earth at all. Though they appear to be stuck in a time loop, they could very well change their path and stop the Earth's destruction. If they do so, the Lighthouse society will cease to exist, because it simply will not be needed.
