How did Reed get the map in the first place? (spoiler)
This I never got. How did he get the map? Where were the others when he took it? Also, why did he take the map in the first place if the only thing he was going to do with it is hide in the middle of nowhere and spend his final days waiting for death on the hill with his telescope. What kind of a life is that?
Not to mention that the people he was waiting for could have come during the night when he wasn't looking...
