Act 5 Scene 2
Friar Lawrence sends Friar John to Mantua to deliver a letter to Romeo, but because he was around the sick he was never able to enter Mantua and was put in quarantine. Because he was apparently "sick" no one wanted to deliver the letter for him. Friar Lawrence then came up with a new plan for Romeo and Juliet.
