summarise and rephrase into bullet points: At his cell, Friar Lawrence speaks with Friar John, whom he had earlier sent to Mantua with a letter for Romeo. He asks John how Romeo responded to his letter (which described the plan involving Juliet’s false death). Friar John replies that he was unable to deliver the letter because he was shut up in a quarantined house due to an outbreak of plague. Friar Lawrence becomes upset, realizing that if Romeo does not know about Juliet’s false death, there will be no one to retrieve her from the tomb when she awakes. (He does not know that Romeo has learned of Juliet’s death and believes it to be real.) Sending for a crowbar, Friar Lawrence declares that he will have to rescue Juliet from the tomb on his own. He sends another letter to Romeo to warn him about what has happened, and he plans to keep Juliet in his cell until Romeo arrives.
