BFFs

BFFs is a side mission found in Sanctuary. Four friends are accusing one another over who stole the money they had looted together. One member of the group asks for your help in finding the culprit. Upon accepting the quest, Marshall Friedman will contact you by echo and inform you that only one person will state the truth and that the other three friends are lying. He asks you to work out who is the thief and shoot them.

Objectives

 * Question O'Cantler
 * Question Jim
 * Question Sam
 * Question Lindy
 * Shoot Thief

Strategy
Only one member of the group will tell you the truth, all the other members are lying.

Basically, what each member says is as follows There are a few different ways of deducing the thief.
 * Sam: O'Cantler stole the money
 * Lindy: 'Sam stole the money'
 * O'Cantler: Sam is lying
 * Jim: I didn't steal the money
 * 1) Take both O'Cantler's and Sam's statments to be false. This causes a paradox (e.g. "This statement is false") because O'Cantler says Sam is lying but if he himself is lying then Sam must be telling the truth but since we took Sam's statement to be false a paradox occurs. From this we can deduce that the truth teller must be either Sam or O'Cantler. Because of this, Jim and Lindy must be lying and since Jim's statement 'I didn't steal the money' has to be taken as false this means that Jim must be the thief.
 * 2) Examine what each character is carrying on their back. Jim is wearing a large backpack with a dollar sign on it. From this evidence one may assume that Jim is the thief.

Once the player shoots Jim, a large amount of money piles will drop from his corpse. Shooting anyone else will cause Jim to reveal he was the culprit and run away, though as in Won't Get Fooled Again the reward for the mission will be given anyway, further proving that in Sanctuary as long as justice is done it doesn't really matter who it is done to.

Completion

 * "You defused a tense situation."
