Mr Stalling says that he is waiting for a sign from God, when Walter O'Brien visits him at the ark. Walter imparts a tale about when the water has risen, men will come by in a boat to take him and the two Mrs Stallings's to safety. They will not go, because they are waiting for a sign and they will drown. And God will say, I sent you a boat, what more did you want? This story also appears in the The West Wing season one episode "Take This Sabbath Day" and is told by the Karl Malden character, Father Thomas Cavanaugh.
When Eddie and Arnold pay a visit to Jigger, after he stops shooting at them, Eddie and Arnold approach him. Jigger is sitting in a chair and holding a shotgun on his lap and not moving. A few shots later, the shotgun is in upright position with the butt on the ground. After they look at Jigger's feet, there's no sign of the shotgun so he must be holding it on his lap, again.
Jigger can be heard pumping a shotgun between shots, but when we approach, we find he has a double-barrelled shotgun, which makes virtually no noise during reloading.
