She's in Jade's arrival story (and probably the rest of Team Kimba's). She drops in on Angel and Lily while Lily is preparing for a date. Wallflower secures a plane ticket so Angel can accompany her back to her great-uncle's funeral; Angel was her roommate before Wallflower moved in. She was part of the battle with the Monkey King. Go-Go is apparently addicted to Honeydew Lollipops, because she wanted the shopping expedition to Boston to bring some back for her. Go-Go gives Hippolyta a lollipop during a break from Hippy getting to know Carmilla better. Much better.
