Secret's Links
They are the best of fashionably devilish friends, and love to go hunting for treasures together in Acadia's strange world. Together (with a little advice from an unwitting Kayne) they learned how to hack Freia's AI and get her to design the Kreechur Brand of mods.
They were friends as tots, and Secret holds a lot of Kane's heart in her way. They pulled a few too many pranks for her not to have plenty of blackmail material. They still get along since the naturally bubbly Secret isn't really one to be malicious. She's completely immune to Kane's short, grumpy attitude.
They were friends at an age where it's easy to forget, so Kane has few memories of his time with Secret - though she seems to remember a lot of embarrassing things from his past. He appreciates how immune she is to his unfortunately grumpy personality.
