The time has come for the ultimate face off between Eli (José Zúñiga) and Robbie (Gabriel Luna) in the upcoming episode of Marvel's "Agents of S.H.I.E.L.D."

In the episode titled "The Laws of Inferno Dynamics," the synopsis (as per CarterMatt) reveals that Robbie is finally ready to take down his uncle and save not only himself but also the rest of the people in the Los Angeles area. Eli is planning something huge, and with the powers he got from the Darkhold, he will likely succeed. The S.H.I.E.L.D. agents know they are way over their heads in this one. How can they defeat someone who can make matter appear with a slight movement of the hand? Eli seems to be unstoppable, but there might be a way to do it.

As per the promo, Coulson (Clark Gregg) thinks the only way Eli can be defeated is by sending their strongest fighters – Robbie, Yo-Yo (Natalia Cordova-Buckley) and Daisy (Chloe Bennet). They alone can handle Eli's powers. The women's Inhuman abilities will be useful in the fight, whereas Robbie is hoping the Spirit of Vengeance will abide by its promise.  

In the last episode, Robbie agreed to become the Spirit's host once again but there was a catch. It would have to help him take down Eli first. Robbie knew there was no other way. His uncle must be stopped, and if it means selling his soul to the devil once again, so be it.

The entire team will be on red alert. Eli is dangerous. He thinks he has turned into a god because of his powers. In the clip, Robbie tells him he had better be, since the devil is coming after him. Coulson and the others are hoping he will be able to stop Eli. With many lives at stake, they cannot afford to have the villain succeed in his evil mission.

Marvel's "Agents of S.H.I.E.L.D." season 4 airs Tuesdays at 10 p.m. EST on ABC.
