Robbie's (Gabriel Luna) true story will finally be revealed in the upcoming episode of Marvel's "Agents of S.H.I.E.L.D."

In the episode titled "The Good Samaritan," the synopsis (as per CarterMatt) reveals that Robbie is finally ready to tell the story behind his deal with the devil. S.H.I.E.L.D. had trouble accepting what Robbie had been claiming at first, but after the bizarre situations that they've found themselves in, the members are close to considering Robbie's words. He is forced to stay with Coulson's (Clark Gregg) team to find his uncle Eli (Jose Zuniga), who has gone missing. Robbie suspects that Lucy (Lilli Birdsell) is the culprit.

As per the promo, Robbie says he is ready to reveal his secret. But then again, his brother's arrival may have triggered something in him. Daisy (Chloe Bennet) is shown leading Gabe (Lorenzo James Henrie) in one of S.H.I.E.L.D.'s white pods. Robbie tells Gabe he deserves to know the truth. Glimpses of a car chase are shown, culminating in a horrific crash. Gabe's bloody face is visible inside one of the cars. The scene appears to be part of Robbie's memory. Later on, Daisy tells Gabe to close his eyes, as Robbie transforms into Ghost Rider in front of him.

Meanwhile, Director Mace (Jason O'Mara) is curious if Robbie is an Inhuman. He asks Coulson about it, but the other man says Robbie claims to have formed a deal with the devil. Like the rest of S.H.I.E.L.D., Mace will likely doubt Robbie's story until he proves it to himself. The director is also expected to deal with Senator Nadeer's (Parminder Nagra) threat. The latter previously showed him footage of Daisy working with the team. Nadeer was blackmailing Mace that she would release the video soon.

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