The reason you were confused is that pronouns, correctly used, can somewhat help de-obfuscate which person is the subject, which is the object, and so on. Imag

The reason you were confused is that pronouns, correctly used, can somewhat help de-obfuscate which person is the subject, which is the object, and so on. Imagine you have a man, another man, and a woman. "He hit her" tells you the subject and helps narrow down who was doing the hitting, and that there was one witness. "She hit him" tells you who did the hitting and narrows down who was hit, and that there was one witness. "It hit it" (using "it" as a pronoun, Blindsight-style, as well as others) only lets you know that hitting has happened and that one person was a witness. "They hit them" tells you that hitting has occurred. No indication if it was a group thing or not, if there was an uninvolved witness.
