Personal History: Standard searches reveal no Imperial citizenship record for a "Raina Temple," but the usual caveats apply--our data on the Imperial populace remains sadly incomplete. Temple's skills and attitude suggest Imperial Army training, but her presence inside the Chiss Expansionary Defense Force is extremely unusual; neither the CEDF nor the Imperial military is known for its transfer programs.
Analysis: Personable and bright Imperial military cadets don't end up embedded with aliens at the far edge of the galaxy without good reason. Temple could be a plant, but it's just as likely she's been intentionally forced out of the picture. Best-guess personality profile suggests she's a typically patriotic example of the rank-and-file Imperial military--a true believer in Imperial superiority and duty. No matter how easygoing or empathetic she may be at times, the needs of her nation have to come first.
