The structure of Invincible has never been its strong suit. The first couple of episodes build classic superhero origin stuff, the next few see Mark fight one villain after another, and then the finale unpacks that whale of a final reveal. Season two spent two episodes unpacking everyone's new emotional state while letting Mark add a few antagonistic notches to his belt. Episode three sharply escalates multiple plotlines, giving characters time to breathe and ending with a breathtaking conclusion.
