“Marvel’s Agents of S.H.I.E.L.D.” is bringing viewers back to where the Hive story began. A new sneak-peek video from the Season 3 finale shows two agents on Maveth, the planet that Hive was trapped on for centuries. But it isn’t clear exactly why or how they traveled to the planet.

Sneak Peek No. 1

Daisy (Chloe Bennet) and Coulson (Clark Gregg) are in one of the containment modules on the blue planet. Daisy is frantically trying to work with some wires while Coulson talks to her. “How long do you think we can survive in here?” Coulson asks. “We’re the last ones. You always find a way to survive, don’t you?”

“It’s in our blood,” Daisy says. She touches a necklace. It’s Elena’s (Natalia Cordova-Buckley) cross, the one that was floating in Daisy’s vision of the future. “I knew someone was going to go. I just didn’t know everyone would.”

Daisy says she is going to hack into the module and pilot them back to Earth. Coulson claims they’re already there.

Sneak Peek No. 2

The next clip is much less confusing. Elena and Mack (Henry Simmons) prepare for a mission. Elena, also known as Yo-Yo, thinks Mack is working too slow. “If this doesn’t work, the hostages won’t matter and neither will we,” Mack says. “If Hive get through here, we’re all dead. Or worse.”

Elena holds up wristbands that are apparently some kind of weapon and ask Mack if he’d use them. Mack looks guilty. It must be a fail-safe for the Inhumans. Coulson wouldn’t let the super-powered agents go after Hive if they could fall under the mind control. Elena isn’t offended that Mack is willing to follow orders.

“Good,” she says. “Because I’d rather die than be anyone’s slave.”

Mack says the mission is too dangerous and gives her the cross necklace back. Could Elena be the one wearing it in Daisy’s deadly vision of the future? Or will Elena refuse to take the jewelry back?
