The student walks slowly toward Raven, pulling something from his pocket. It's a hand-held device, but much too bulky to be a calculator. It's got a keypad on the top and a sort of window on one end, which the student keeps aiming toward Raven. There's an LED read-out above the keypad and a red flashing light underneath that. The student is wearing a pair of headphones that are jacked into a socket on the butt of the device.
