In reply to my amazing teacher's blog post, I am going to answer her question with text from the play supporting my response.
"Where is Macbeth at the end of Act I?"
By the end of Act I, we see Macbeth slowly adjusting to his new life (as predicted by the weird sisters). He is now aware of his title as 'Thane of Cawdor', and so he also lets Lady Macbeth know through a letter "Whiles I stood rapt in the wonder of it, came missives from the king, all who hailed me 'Thane of Cawdor'/ by which title, before, these weird sisters saluted me..." Lady Macbeth plans for Macbeth to murder King Duncan, so that he can be King. By the end of Act I, we witness a cowardly Macbeth as opposed to everything he seems like on the outside - a brave warrior in shining steel armor. Although Macbeth has won many physical wars, he is now at an emotional war with himself when his wife discusses her plan to murder King Duncan. "False face must hide what the false heart doth know."
