Yandere Traits Edit
In "Alone at Sea", Jasper begs Lapis to re-fuse with her, claiming they were better together than apart. She claims that Lapis is a monster, and only she could handle that power. Jasper appears sycophantic, claiming that she has changed. After being rejected, she became enraged and attempted to "shatter" Steven until she was thrown back into the ocean by Lapis.
