Rosse is the Thane who brings Duncan news of the Norwegian invasion and of Cawdor’s complicity in it.
He is sent to have Cawdor executed and to give his title to Macbeth. He is present the morning after Duncan’s murder, and predicts Macbeth’s accession. Unlike Macduff, he decides to attend the new king’s coronation. Present at Macbeth’s feast, he is the first to note that Macbeth is acting oddly. He attempts to comfort Macduff’s wife, insisting on the flown thane’s wisdom and nobility, but not daring to stay too long with her. Gone to England himself, he at first tells Macduff that his family is well; it is not until he has received assurances from Malcolm that an invasion is imminent that he reveals that they have been murdered. He is present at the final battle, and brings Siward news of his son’s death. A glib-tongued fellow, he has a knack of being on the winning side and at placing himself first.
