Ghost Rider is back for Marvel's Agents of S.H.I.E.L.D.season finale, and he’s got some answers about Aida!

“There was a tear in the dark world when she was created,” Robbie Reyes (Gabriel Luna) tells agents Coulson (Clark Gregg) and Daisy (Chloe Bennet) in this sneak peek from S.H.I.E.L.D.’s season four closer. “That’s how I escaped.”

We last saw Robbie earlier this season as he let the Ghost Rider take over, allowing him to drag his uncle, Eli Morrow, to another hellish dimension. Morrow, an engineer, had hoped to harness the mysterious powers of the Darkhold in order to make himself “a god,” a feat that Dr. Radcliffe’s (John Hannah) former assistant, Aida (Mallory Jansen), has now mastered after returning from the Framework.

“So you’re saying Aida’s made of the same stuff as the Darkhold?” Coulson asks of the terrifying former android, who, in recent episodes, used the ancient book to build herself a synthetic human body, transferring her all-knowing consciousness and adding human emotions.

“Yeah, and the Rider wants to send them both back to where they came from,” Robbie reveals.

But it turns out, that feat -- and ultimately, beating Aida -- might not be as simple as it sounds. Check out the video above to see more!

Marvel’s Agents of S.H.I.E.L.D.’s season finale airs Tuesday at 10 p.m. ET/PT on ABC.
