Romeo is puttin a ring on Juliets finger
After the party ends, Romeo can't stop thinking about Juliet, so he ditches Mercutio and Benvolio and heads back to the Capulet house. Mercutio and Benvolio try to find Romeo after the party. They assume that Romeo is going to find Rosaline. Afterwards, they crack a lot of dirty jokes at Romeo's expense. Mercutio is offended that Romeo left them.
Romeo goes to see Friar Lawrence and right away Friar can see Romeo is beat and thinks he has been with Rosaline. Romeo says no and tells him he now loves Juliet and wants to marry her. Friar is weary of this sudden change. Romeo says Juliet returns the love he gives to her. Friar still very weary eventually agrees to marry them.
