Derek is plagued by nightmares of mumification rituals and Rachel feels guilty at Kat's apparent lashing out against her in the form of her imaginary friend. Everything comes together when it is discovered that the Egyptian Prince was really the Pharoah's only daughter killed and buried without a name. Only to leave them wondering...where is Kat and is Kali really just a figment of her imagination??
