The Good Samaritan has moved on. In the first half of Season 4, "Agents of S.H.I.E.L.D." made it abundantly clear that Robbie Reyes was not the first Ghost Rider when a leather-clad man with a motorcycle and a flaming skull brought him back from the brink of death, but that's where that man's story begins and ends, at least according to executive producer Jeffrey Bell.
Speaking to IGN, Bell explained, "There is a tradition within the comics that there's been many Ghost Riders and our take on that was they're not simultaneously a tribe of Ghost Riders but that it's passed. The Spirit of Vengeance is passed from person to person. In that respect, at least our intention was that the Spirit of Vengeance was passed from one person to another, and who passed that on, there are suggestions within the storytelling... That's as far as we're going to take that part."
The "suggestions" Bell refers to in his statement were dropped over the course of Season 4's "Ghost Rider" arc, and they pointed a finger at Johnny Blaze. As mentioned above, the Good Samaritan had Blaze's signature look: the leather jacket, motorcycle and flaming skull. What's more, the Darkhold was discovered in a basement lined with Quentin Carnival posters and old motorcycle parts and helmets, which all refer to Blaze's origin as a motorcycle stunt driver. Though he was never mentioned by name, the show made it pretty clear that Robbie's Good Samaritan was, indeed, Johnny Blaze.
As such, that means we won't see Blaze come back to the show anytime soon. However, that isn't the case for Robbie Reyes; though he disappeared into another dimension in the mid-season finale, the cast and crew of the show has teased Ghost Rider's return. For now, though, the show is in the middle of its LMD storyline, where Holden Radcliffe has set his Life Model Decoys against S.H.I.E.L.D. in order to steal the Darkhold and use it for his own nefarious purposes.
