Cartoon Network's teaser trailer for a brand-new episode of "Steven Universe" has revealed a shocking plot twist: Sadie is missing, and someone is looking for a father.

In the next clip, he finds out that his friend went missing. The trailer also showed Steven being smashed against a tree and Pearl crying uncontrollably.

Toward the end of the clip came another surprise for fans. A small voice can be heard asking, "Are you my dad?" This question shocked fans, and it has led many to ask who said the question.
