Question: Olaf fades away once Elsa dies because he can't live without her magic. He is only revived by Elsa after she revives. The post-credit scene shows Olaf in Elsa's ice palace telling a story to Marshmallow, the giant snowman and the tiny snowmen. How is it possible that Marshmallow and the tiny snowmen are still alive after Elsa froze to death? Did Elsa guess they have faded away too and managed to revive them? Did she even have to rebuild her ice palace?
Question: Minutes after Elsa freezes, Olaf flurries away, and turns into a pile of ordinary snow. Why? Is it because he can't exist without Elsa?
