Before Soldier Boy busts out of the Russian facility, we meet him via flashbacks. This is how we learn that Vought’s first hero had a sidekick:  Gunpowder, a teenage firearms enthusiast. Gunpowder ends up being much more important in the present-day’ when he tangles with Butcher, but we briefly see a younger version of him helping Soldier Boy on the Barbary Coast. Since he wasn’t around as long, this actor might be a little harder to recognize than Jim Beaver, but indeed, another “Supernatural” alum has entered the fray: Gattlin Griffith.

Way, way back in the first decade of the “Supernatural” run, when Kripke was still at the helm, the Winchesters were caught in the middle of a war between heaven and hell that put them face to face with the anti-christ, aka, a ten-year-old boy named Jesse Turner (Griffith). Castiel introduces Jesse as a half-human, half-demon child with essentially unlimited powers and concludes that he has to be killed before he gets any stronger. But being absolute softies, the Winchesters refused — instead, they told Jesse the truth and offered to protect him. In the end, Jesse ran away — hiding from demons, angels, and Winchesters alike.

This ended up becoming one of the infamous loose ends that “Supernatural” never got around to tying up. It always seemed like the whole anti-christ thing might return to bite them in the ass — but he never did. Perhaps after Kripke’s departure, in the shuffle of finding a new showrunner and direction for the story, Jesse was forgotten. Kripke remembered and even kept Gattlin Griffith’s number because he called him up just in time to reunite with Jensen Ackles. Griffith marked the occasion by sharing an Instagram post, tagging Ackles to say: “long time, no see.”
