Auerbach also rides hard on DQ's madness to the point of invalidating anything that happens in the novel to be of DQ's actual design or influence. That is, the events in the inn where at least three couples are reconsiled and lots of people are made legitimately happier due to DQ, none of that matters. Nor is DQ's standing up for Marcela (who recall, already spoke up for herself eloquently) against the fuckboy shepherds meaningful.
No Auerbach. You are wrong.
