The S.H.I.E.L.D. agents will have to seek the help of an unlikely ally to pin down the Ghost Rider in the next episode of "Agents of S.H.I.E.L.D." season 4.

In the upcoming episode titled "Let Me Stand Next to Your Fire," the vigilante of East Los Angeles will finally come face to face with the former S.H.I.E.L.D. director. But Coulson (Clark Gregg) could still not contain the wrath of Robbie Reyes's (Gabriel Luna) evil alter ego, Ghost Rider, which is why the agents need the support of an unexpected alliance in order to stop the villain from causing further chaos.

In a promo image posted by International Business Times from ABC, Coulson appeared to be visiting someone in prison. Since the guest listing for the episode that The Futon Critic posted revealed that Jose Zuniga will appear as Robbie's uncle Eli Morrow, it could be speculated that the agents will work with him in order to capture the Ghost Rider.

But can Eli really help the agents capture his nephew, even if he was also known to be possessed by the vengeful spirit of the Ghost Rider in the comic books?

Former S.H.I.E.L.D. agent gone rogue, Daisy (Chloe Bennet), is also expected to work with a familiar face to finish her job to stop the Watchdogs from creating chaos. She will most likely join forces with another Inhuman Hellfire (Axle Whitehead) to do her tasks. But could she really trust Hellfire this time?

The synopsis of the upcoming episode reads: "As Ghost Rider's quest for vengeance brings him into an explosive confrontation with S.H.I.E.L.D., Coulson and Mack (Henry Simmons) must rely on an unlikely ally in their time of desperate need; and Daisy reunites with a familiar face to stop the Watchdogs."

The upcoming episode of Marvel's "Agents of S.H.I.E.L.D" season 4 will be aired on ABC on Tuesday, Oct. 18, at 10 p.m. ET.
