What Does The Ending Of Black Panther Really Mean?

3. Everett Ross Owes Wakanda A Debt

In the comics, Everett Ross is appointed as escort to T'Challa and his Wakandan delegates when they come to the US, but he ends up becoming a trusted ally and friend to the king to the extent that he is left as Regent of Wakanda in T'Challa's absence.

In the MCU, Ross was still working for the CIA and was still investigating Vibranium trade (on the assumption that it had been stolen from Sokovia) and his allegiance is very much to his mother country. But now that he's had a bullet intricately cut out of his spine that should have either killed or paralysed him, he's very much a Wakandan now.

And him joining in the fight to stop the Wakandan tech being flown out to Hong Kong, England and America proves how much his status has changed. He might still be in the employ of the US government, but he's now just as much T'Challa's man as he was in the comics.
