Friar Laurence asks Friar John to deliver a letter to Romeo explaining the plan to fake Juliet's death.
Romeo wants the Friar to marry him to Juliet.
Juliet's nurse.
Friar Lawrence wants Romeo to do different things depending on what part of the play you are talking about. When they first meet, the friar tells Romeo to go slowly in his relationship with Juliet (as if!).
Romeo plans to visit Friar Laurence the next day to ask him to marry him and Juliet.
Juliet's nurse.
Juliet will return to Friar Lawrence's cell to ask for a way to reunite her with Romeo after he has been banished. It's like they are to be remarried.
He says that if he's at fault for any of the mishaps that overtook Romeo and Juliet, he should be put to death. The Prince doesn't appear to take him up on it, though.
The friar doesn't ask him if he has spent the night with Juliet. With Rosaline, not with Juliet.
Friar Lawrence asks for an iron crowbar to open Juliet's tomb in order to rescue her and prevent her from being buried alive. He wants to make sure that Juliet is safe and prevent her from suffering any harm while also attempting to reunite her with Romeo.
Juliet goes to Friar Laurence's cell in the play twice. The first is to marry Romeo and the second is after she learns of her prospective marriage to the County Paris. The latter time she seeks his help to stop the marriage from happening so that she may remain faithful to her Romeo and bee reunited with him.
She is confused and desperate because she does not know what to do and was going to kill herself if Friar Lawrence did not come up with a plan to help her.
Friar Lawrence cautions Romeo because he is afraid he'll get his heart broken and fall into depression again like he did because of Rosaline. He also thinks Romeo is moving way too fast with Juliet because they're already getting married and they barely met each other.
