With the murderer now in custody, Black Panther will see T’Challa returning to Wakanda and embracing his new responsibilities as king of the technologically-advanced African nation.
T’Challa’s father, T’Chaka, died during Helmut Zemo’s attack on the signing of the Sokovia Accords during Captain America: Civil War.
So on top of keeping his people safe as the Black Panther, T’Challa must also work to keep them united and ensure that they’re not led down a dark path.
As Ryan Coogler pointed out, this comes at a time when others have their own ideas on how Wakanda should move forward.
