Ema Skye is a forensics scientist with the Los Angeles Criminal Affairs Department, generally cheerful and optimistic, especially when it comes to forensic science. She is more withdrawn as a detective, disliking talking to people on any subject other than forensics, though she mellowed out after finally getting her dream job. Even with her time as a detective being a relatively low point from her perspective, she would immediately cheer up if the opportunity to talk about forensics arises.
