The water’s impact knocks the two women unconscious, but luckily, Ramonda comes to her senses quickly and paddles both of them up to the surface. Shuri, Okoye (Danai Gurira), and Nakia rush to the throne room and attempt to revive the duo. Thankfully, Riri rouses and seems to be doing fine, but unfortunately, Ramonda dies at the hands of Namor’s attack.
