A fight between O'Brien and Elroy
A quarrel between Jefferson and James
An grudge between Jensen and Strunk
The death of Strunk by Jensen
He was afraid that Strunk would take his revenge with a gun
He didn't want to alarm O'Brien and cause trouble
He didn't want to seem like a very tough man
If one of them got killed, the other would bury him
If one of them was severely injured, the other would treat his wounds
If one of them was captured, the other would report it to his family
If one of them was injured so madly as to be in a wheelchair, the other would kill him.
Jensen had gone crazy.
He thought that Jensen would keep his word.
He knew that Jensen was going to kill him and take his revenge.
Jensen was his enemy.
