RE: Riddles
Were Person B and C's arm cut off on the deserted island?
Does the arm in the box belong to anyone relevant to the riddle?
Are there any non-human creatures relevant to the riddle?
Summary of important answers:
The body part in the box was an arm. Person C & B are missing an arm because they were going to be used for food, and all three were stuck on a deserted island at one point. Person B & C's arms were cut off by person A, and B & C are not mad at A for cutting their arms off. The arm in the box does not belong to A, B, or C, and these three are not still stuck on the deserted island.
Did person C want his arm back?
