Yeah NO sense.
Like the way the Queen makes a whole plan to rescue Shuri and puts it into motion before meeting with Namor, who then tells her that Shuri is in no danger.
Wouldn't it have made more sense for her to meet with Namor before doing anything to confirm Shuri's well-being?
Then after all that shit goes down, no effort is made to prepare Wakanda for a possible retaliation from Namor. Like huh?

And then the whole plan for fighting Namor and his ocean people... in the middle of the ocean.
The way Riri Williams was damn near shoehorned into this movie was just terrible. Her being such a pivotal part of this movie was a very confusing thing to do.
