In Macbeth, Angus does not speak in Act I, scene ii. Create three lines for this character (if he were to speak in the scene) & indicate the point where he would say each one.
In Macbeth, Angus is a nobleman, loyal to Duncan. Ironically, Angus enters the dialogue in Act I, scene iii and he is the one who tells Macbeth of his new title, that "our royal master," (I.iii.101) Duncan, has inferred upon him, as a show of thanks for his valiant efforts against the enemy. Angus has no difficulties explaining how the current Thane of Cawdor has committed treason and so "bears that life which he deserves to lose," (111).
Had Angus been inspired to talk in Act 1, scene ii, he may have offered some words about the treacherous Thane of Cawdor, having sided with the "Norways' king," (I.ii.61) First of all, his presence would need to be noted after Ross says "God save the King! (line 47), and Angus could proffer his words immediately afterwards:
Hail, King of Scotland!
This could be considered to be a forewarning of what is to follow and relevant because it is Angus who will tell Macbeth of his new title. Furthermore, at the end of the play, Angus is among the noblemen and soldiers who declare Malcolm to be king. At the end of scene ii, after Duncan declares,"What he hath lost, noble Macbeth hath won,"(68), Angus could add:
"To bring great glory to our worthy and most noble king, Macbeth will deserve all that he may hereafter bring, in deliverance of all that is fair as we now remove that which is most foul."
This refers to the replacing of the Thane of Cawdor with Macbeth. These words reinforce the symbolism contained in the well-known words, "foul and fair." As Angus has such a small part, it would be fitting that it could add such importance to the plot and outcome of the play.
