Lol, good breakdown of their convo, you summarized it to a T.
Both Shuri and T'Challa had good showings in this book. Several folks were hoping that T'Challa would encounter the Midnight Angels, but honestly, what good would that do? Shuri had to be real aggressive just for them to listen to her. They wouldn't even give T'Challa a chance. It would've been a fight from the jump, and the MAs and their followers would feel inspired and all that.
Getting the MAs back to the fold required a good amount of aggressiveness combined with outright threats, something Shuri is good at (see the Desturi in Doomwar and the Wakandan-Atlantis war). Meanwhile, getting Changamire on monarchy's side required a good amount of diplomacy and guiding Changamire towards a certain direction without putting hands or bloodshed, something T'Challa has shown to be good at throughout his publication history.
The monarchy got some well-needed Ws this issue.
As crazy as it sounds, I can def see this run translating very well on television, especially with a few tweaks to the script.
