Why do the interrogators put a red nose on victim in swansong?

The interrogators in "Swansong" do not put a red nose on the victim. This detail is not present in the game's story or lore.

Perhaps you are thinking of a different game or piece of media?

Could you please clarify the context or provide more details about the "victim" and the "interrogators" you are referring to? This would help me understand your question better and give you a more accurate answer.
