Final answer:
Lennox's interjection in Shakespeare's 'Macbeth' is significant as it suggests the guards are Duncan's murderers and conveys the unnatural chaos resulting from Duncan's murder, highlighting the play's theme of disrupted natural order and immediate mistrust.
Step-by-step explanation:
Lennox's interjection following the discovery of King Duncan's murder in Shakespeare's Macbeth provides critical information on the event and sets a somber mood for the scene.
By describing the bloody scene in Duncan's chamber and the appearance of Duncan's attendants with their hands and faces 'badged with blood' alongside unwiped daggers, Lennox suggests that these attendants could be the perpetrators.
This observation contributes to the initial framing of the guards as the murderers by Macbeth, who orchestrates the scene to divert suspicion from himself. Furthermore, the unnatural events Lennox mentions, like chimneys being blown down and screams of death, underscore the play's theme that regicide has disrupted the natural order.
Lennox's descriptions serve as an ominous reflection on the chaotic state of affairs and the immediate suspicion and mistrust that falls upon those closest to Duncan. The context of treachery and turmoil is effectively conveyed through Lennox's disturbed and disjointed recounting of the night's events.
