If I were to tell you that Elsa actually died in the final of Frozen II? In the cave of past memories, she disregarded the warning and sacrificed herself for the spirits by delving deeper to discover the truth. This is also why Olaf began to fade as he lost Elsa's magic. In fact, Anna even says this line: 'The dam broke and after the five elements united in the sky, Elsa's frozen form is shattered, but we witness the moment she actually died when she fell even deeper. When she reunites with Anna on the shore, she is no longer in human form but in the form of water and ice memories, essentially transformed into the fifth spirit. And please pay attention here, because she doesn't answer 'yes' anymore because she is now just a spirit. In the final scene, Anna takes the crown because Elsa cannot be the queen anymore. So why does she send a message to her sister with the wind spirit? Because the world of humans and the world of spirits can only communicate in this way.
