After Romeo had all of his supplies to go on his quest, including the poison, he had realized that he had no more money left, and he had no way to travel. Romeo then decided to steal a horse to get back to Verona. He then found out that the horse he stole was a police horse. He had to leave Mantua quickly. There became more obstacles in his journey.
On Romeo's journey, he found Benvolio in the Outskirts of Verona. Romeo then told Benvolio what his plan was, which included Romeo dying. Benvolio felt lost without Mercutio, and guilty about confessing to the Prince that Romeo had killed Tybalt.That put a huge burden on his shoulders and with Romeo dying made it worse. Benvolio felt a feeling of a hatred towards life. He wanted to commit suicide.
Benvolio then decided a life without friends or a family is a life not worth living. Benvolio then decided to die in that time. He asked Romeo if he had enough poison to barely kill Romeo and Benvolio. Romeo gave some of the poison to Benvolio, who then died right on the streets of Verona. This impacted the relationship between Romeo and Benvolio deeply.
Romeo has been spotted by Lady Capulet. She is afraid Romeo will cause mayhem to the Capulet Tomb. She thought this because when Romeo killed Tybalt he was banished from Verona, but Romeo is heading to the Tomb. Lady Capulet calls to someone to protect the bodies of her Kinsmen.
Lady Capulet informs Paris to follow Romeo to protect Juliet and Tybalt to honor their family legacy. Paris takes his mighty horse and leaves swiftly to protect his love, Juliet. Paris is ready to protect her at all costs, even to his own death. Lady Capulet then sends a public message to all of Verona that Paris is guarding the Tomb, for fear of Romeo shaming the Tomb.
The Montague messenger finds Romeo on the way to the Capulet Tomb and the messenger tries to warn Romeo that Paris is there guarding the Tomb. Romeo was so distracted about seeing Juliet, he did not heed the messenger's warning.
