The audience knows Lysander deserts Hermia. However, Hermia, with her warped by sleep views, assumes Demetrius must have slain Lysander as the most plausible explanation for Lysander’s absence. The audience sees Hermia’s mistakes and understands that gathering the facts and determining the truth makes a worthwhile endeavor.

Shakespeare also warns the audience against dismissing the truth merely because reality does not match his or her expectations. Bottom completely dismisses any notion of truth in the night’s events. In rejecting the truth, the audience understands that only the fool rejects the improbable reality.
