In Scene 2 why does Friar panic when he finds out the letter was not yet delivered to Romeo and why is this a key turning point

Frei panics because Romeo can believe that Juliet really died and do something very foolish, besides, Juliet would wake up and Romeo would not have gone to get her. This is a fundamental turning point in history because it shows that the whole plan for the couple to be happy is going wrong.

Explanation:

Frei devises a plan together with Juliet, so that she can escape and live happily with Romeo. This plan includes Juliet pretending to die, while the friar sends a letter to Romeo explaining about the plan and how he should get Julieta.

However, he discovers that Romeo never received the letter, the eu puts the whole plan to waste, in addition to encouraging a very horrific result to be stimulated. This terrifies the friar about how everything will be solved.

you need to explain that more, your grammer just needs to be close to perfect.
