Clark Gregg and Chloe Bennet

In television circles, Seasons 1 and 2 of a show are often seen as the “origin story”; it isn’t until you get to Season 3 that most beloved shows (“Seinfeld,” “Friends”) really gain their confidence and hit a stride.

Since “Marvels Agents of SHIELD” is essentially a superhero TV show, stars Clark Gregg and Chloe Bennet know that theory all too well — and as they get ready to unveil the first episode of Season 3 (Sept. 29 at 9 ET/PT on ABC), they say it’s time to get past the appetizer and move on to the meal.

“We just finished our fiftieth episode,” Gregg, who plays beloved Marvel character Agent Coulson, tells Zap2it. “And while I’m proud of some of the stuff in Seasons 1 and 2, I think that’s legit. I think the real meat of what we’re going for here [is about to start]. The show constantly re-invents itself, like a comic book. But I feel like what we’re getting into this season is what the show has always been driving toward.”

“That being said, I don’t think you would fully appreciate this season without those other two,” adds Bennet. “You really get to learn the ins-and-outs of all the characters [in Season 1 and Season 2].”

“Season 3, episode 301,” grins Gregg, explaining where things start out. “It pays off a bunch of stuff you saw at the end of last season. Somebody — I don’t want to say who — knocked down a carton of alien Terrigen crystals into the ocean. Which ended up in some fish, which was made into fish oil. So now, there’s an outbreak of Inhumans.”

Of course, Gregg is referring to his interview partner, and Bennet playfully hides behind her lapel.

“The Inhumans are genetically different humans who take this substance into their body, then wake up one morning with powers, for good or evil,” Gregg explains. “And Coulsen assigns a team that includes — well, used to be Skye, now Daisy, in fact Quake. Along with the giant and spectacular Henry Simmons as Mack to find these new people and figure out if they’re good super people, or bad super people.”

No matter what happens in Episode 301, Gregg and Bennet say to stay tuned. Completely out of context for spoiier-weary-fans, they offer the following promise about Season 3.

“I think the best part about this season is the dynamics of the character relationships have changed,” says Bennet, who plays the identity-shifting Daisy/Skye/Quake. “It feels like there’s a bit more focus on the relationships, whether they are platonic, or if there are love sparks — everybody’s getting some action, and I don’t mean stunts.”

Clark, flashing a wide grin, agrees: “Welcome to level sexy!”
