Now a second half with Shuri, Happy and Pepper could have explored those chars more, but as is, this was What If Killmonger Won?
In which we see the villain, as is the trope, did not change.
As his relationship with Tony grew, I would have hoped he might have seen a different path. He was annoyed Tony didn't see him as a Black man, but ignored that Tony saw him as an equal. He didn't really pause before sinking that spear in.
What If Killmonger got Tony to actively support Black Lives Matter. What kind of crazy over-blown solution would they have gotten to? Coptrons patrolling streets, evenly dispatching justice in increasingly disturbing ways as voiced by James Spader.
That's probably the lack in the episode. BP went there. We all knew why Eric was angry and though we didn't like his plan, he had a point. That was all skipped here, and in the end, all we saw was a successful powergrab and vindictive destructiveness instead.
