Being a private investigator is Rachel's best job yet. Secrets are super hard to hide with her set of mind powers. Not sure if she got a passing grade as an instructor and her time as a paramilitary police officer, rebellion leader/zealot, space pirate/bodyguard and adventurer (whatever that is) are not career highlights on the resume. And even though she didn't do anything genocidal as a phoenix host, what kind of Phoenix work did she do besides saving the omniverse that one time?
