 SPOILER: When he talks to Adam Kesher, the Cowboy says: "You will  see me one more time, if you do good. You will see me two more  times, if you do bad.". Justin Theroux said in an interview that  since he didnt have the entire script, but received the pages day  by day, he asked David Lynch if the Cowboy would appear again in the  film. According to him, Lynchs answer was: "I dont know. We will  find out together.".
