Thomas Middleton

I don't know about you guys, but when I read that Act 3 Scene 5 was most likely written by someone else (most probably Thomas Middleton), I was pretty confused. There are a few noticeable differences in the writing. For example, before 3.5, whenever the witches come into a scene, they have a conversation with one another. 3.5 has hardly any conversation, and it is monopolized by an entirely different character, Hecate, whose monologue is completely written in couplets. This contrasts with the previous depictions of the witches.

Thomas Middleton, the supposed "other" playwright, apparently adapted and revised Macbeth. He collaborated with Shakespeare a few times, including on the play "Timon of Athens." Middleton apparently was thought to be second only to Shakespeare himself by a few notable authors of the period.

Did you guys pick up on any other differences?
