As we mentioned earlier, Steve Rogers takes his old friend to Wakanda to be put in a cryogenic sleep until there's a cure for his brainwashing. Bucky Barnes makes another appearance in Black Panther's postcredits scene, in which a bunch of young Wakandan children yell that he, the "White Wolf," is awake. We now know that he's the other "broken white boy" that T'Challa's sister, Shuri, "fixes."
