Having a debate with someone with such an incomplete knowledge of Black Panther is folly. Especially when people lacking in T'challa history refuse to acknowledge when they are wrong.
The ridiculous example of T'challa breaking WS brain washing is just... do better lol. Bast have mercy.
Especially since, the Knife of Chieftains was established by the Godfather... PRIEST. Vol 3, #29
This is a more true example of, "putting the knife where it belongs" considering T'challa actually succeeded. He killed Klaw in this form and was about to delete Klaw from history until a crowd of people stopped him. No bragging. No lack of focus. Pure 10 steps ahead T'challa with a bonus dose of rage, which is nice to see from T'challa here and there. If there is one person that breaks his focus even a bit and gets him emotion, it should be Klaw. Priest understood that because he's good at comics. Coates uses Thunderball to beat Klaw.
Hickman, who actually read Priest's run, pulled the knife from here. Coates, who has very little knowledge of canon pre-Hickman, just pulled it from Hickman. And considering it appears most of this thread didn't even know the Knife of Chieftain's was a thing before Hickman, I really doubt Coates knew it was a thing before hickman lol.
