"Laws of Nature," the first episode for the third season of the Marvel Television and ABC Network-produced series, "Agents of S.H.I.E.L.D.," lived up to its promise that the world will be shocked of the emergence of Inhumans, when it aired on Sept. 29.

Here were the highlights of this season's premiere episode, featured on the summary provided by Comic Book.

Global Terrigenesis

Executive producer Maurissa Tancharoen teased on Entertainment Weekly that there would be "more Inhumans popping up all over the place" in the new season.

True enough, the show opened showing Joey (Juan Pablo Raba), an Inhuman or someone who possesses alien genes that can be triggered by terrigen crystals to exhibit powers, being confused on his new-found abilities. Coulson's (Clark Gregg) agency has extracted him before an opposing team revealed as the Advanced Threat Containment Unit or ACTU led by Rosalind Price (Constance Zimmer) did.

The show also revealed that several inhumans were already enhanced by the terrigen-contaminated fish oil seen being distributed in a large-scale market on last season's finale.

A Strong Opposing Leader in Rosalind Price

The series showcased a formidable leader in Price, who is smart in deducing Coulson's mission as well. She is also seen examining the bodies of five Inhumans, which just showed she can be a character to be feared and someone that will really clash against Coulson's morals, beliefs and principles. She will really be a strong opposing force to S.H.I.E.L.D. as she and her unit has been created by no other than the president himself with a mission to "neutralize alien threats."

Terrigen-contaminated Fish Oil Not Harmful to Humans

Executive producer Jedd Whedon also shared on Entertainment Weekly that the first episode will answer if the contaminated fish oil will be a threat to the normal human beings. In the episode, it said that "poisonous element sank to the bottom of the ocean," making it non-harmful to humans but still an effective catalyst to Inhumans.

A Glimpse of Jemma Simmons' Whereabouts

The episode showed a bolder Leo Fitz (Iain De Caestecker), who is determined to find and bring back Jemma Simmons (Elizabeth Henstridge). In fact, he was the only one still believing Simmons, who was swallowed by the Kree monolith, to be alive. In the last scene, the biochemist is seen as if she is in another world with a "planet and a moon in the sky behind her." Where could she be?

In the second episode, viewers will find out more about Simmons' case, when the team sought the help of an Asgardian, informed Comic Book Resources, citing ABC's sysnopsis.
