Upon his arrival in Twin Peaks, Cooper is enchanted with the place and forms an instant rapport with many of the townspeople - most particularly Sheriff Harry S. Truman and his deputies, Deputy Tommy "Hawk" Hill and Deputy Andy Brennan. While Truman is initially skeptical of Cooper's unconventional investigation methods and other-worldly ideas, he is most often willing to accept Cooper's judgment. Over time, a deep bond emerges between the two; Truman even deputizes Cooper during the latter's brief suspension from the FBI.
