- For the mental patient, see Betty (Haverford).
Betty was high school principal William Hastings' secretary.
Hastings gave Betty a copy of important coordinates, which he and Ruth Davenport had found on behalf of "the Major," a man they had met in an alternate dimension. Dale Cooper's doppelganger was in pursuit of these same coordinates, and he hired Ray Monroe to get them from Betty.
By late September 2016, despite his detainment in federal prison, Ray had apparently succeeded in obtaining the coordinates, and attempted to extort Cooper for $500,000 in exchange for the information. Betty was killed in her car by a bomb planted by Cooper and Jack.
