(Sorry for skipping so many episodes)
Episode 15: she dosen't show in this episode since it's all about Lapis and Steven
Episode 16: she didn't show in this one either since it's about Greg and Rose
Episode 17: the only time Topaz shows is when Jasper does. Topaz attacks her but Jasper is able to get away and Topaz says, "Ever since Japser was on that boat I decided to hunt her down."
Episode 18: Topaz went with Garnet and Pearl to look for Jasper but all she did was basically flirt with Pearl
Episode 19: all Topaz did was hug and reassure Amethyst that she is important
(I don't understand why but I'm having writers block and I'm struggling to add Topaz into the episodes)
