The new trailer for Chloé Zhao's Eternals answers some of Marvel fans' biggest questions while opening up more mysteries to study. The reason why the Eternals are finally coming together after centuries of silence seems to be centered on an "Emergence," triggered by the amount of life refilling Earth after undoing Thanos' genocidal snap of a finger. It's further proof that the consequences of the war against Thanos are still echoing around the world, but this time those consequences are being seen on a global, or even cosmic scale.

The final trailer for Eternals opens with a matter of fact recap of what Thanos did, spoken by Salma Hayak's ageless leader Ajak. But her summary ends with a worrisome new threat. The sudden burst of returned life provided enough energy for something called an Emergence to begin. The Eternals only have seven days to stop this Emergence from happening, and a shot of ecological devastation is the only hint as to what the Emergence may entail.

Whatever this threat is, it's enough to activate the Eternals after centuries of silence. Many of them haven't seen each other since, necessitating a reunion of these cosmic immortals. It brings their individual personalities to the fore, but what it also does is highlight the mournful ripple effects of the Blip.

For humanity, it was five years of dealing with the loss of loved ones followed by the drastic clashes of reintegration. Fans have seen its effects on an individual level through Peter Parker's journey in Spider-Man: Far From Home. He and Aunt May show what life has been like for the returned, trying to get their homes back, and make sense of the fact that many of their friends and loved ones are five years older.

On an international scale, the Blip's economic and social effects were glimpsed in Falcon and the Winter Soldier. The Flag-Smashers represented displaced and disenfranchised people who were pushed aside as confused social services and no small amount of corruption and grift tried to cope with the thousands of people who had suddenly returned. It still showed the problem on a small scale.

To date, only Captain Marvel has made serious note of the fact that the effects of Thanos' genocide went far beyond Earth. The Eternals trailer now seems to promise to showcase that ripple effect on a grander, even cosmic scale while still staying close to home. The Eternals are attuned to life on Earth, aware of its ebb and flow even if they're not permitted to do anything about it unless it involves the Deviants. Glimpses of Earth's history show them at work among humanity, but with less grim fear than they seem to face whatever's coming next. The Deviants themselves are glimpsed, some like mutated forms of life, one unsettlingly humanoid and sentient.

The Emergence, whatever it turns out to be, makes humanity's post-snap return into something like a meteoric impact. Life abruptly surged across the Earth once again, awakening something dire enough to make the Eternals leader, Ajak, concerned enough to regather their family of immortal guardians. The Deviants, too, are on the move, and it's not clear how they tie into the Emergence itself. Whatever else the post-Blip caused for humanity, it was enough to awaken forms of life on Earth that humanity never knew about.

A chilling glimpse of a red Celestial serves to remind viewers that, no matter how close to home the events of Eternals are, there's a cosmic reckoning in store, too. The Celestial motives are frighteningly unclear, and although the Eternals act out of protective and caring instincts, there's nothing human about their creators. Whatever comes of the Blip, the Emergence, and the new Deviant threat, the Celestials are a part of this, too. There's no way to know if Thanos understood the true scope of what he was unleashing on the universe when he snapped his fingers, but the results are now up to the Eternals to face.

Directed by Chloé Zhao, Eternals arrives in theaters Nov. 5.
