I like to think Michael had no idea what was going on the whole time
Just like- him being completely oblivious to the fact that the Afton's, specifically William, are the cause of literally everything that's gone wrong in the series.

Also some more doodles

(In case you can't read it because I suck at taking pictures)
William: Why do you watch that show, Michael? It's Trash.
Michael: The Immortal and The Restless is by far the best thing on television, father.

William: You are a mistake.
Michael: You've said that a million times.
William: Because it's true.
