Capulet, Paris, and Lady Capulet are talking about how Juliet weeps for Tybalt's death. This is dramatic irony because we know that Juliet is upset because of Romeo's banishment, not exactly Tybalt's death.
We can see that Paris is sympathetic because he's waiting until Juliet has stopped grieving to ask her about marriage.
In this scene we can see how persistent Paris is because of his constant attempts to be with Juliet.
Paris asks about Juliet as a wife and Capulet says it's too soon from Tybalt's death to be thinking about marriage.
At one point, Capulet remarks that even though Tybalt had an untimely death, everyone dies eventually. This is foreshadowing because Paris, Romeo, and Juliet will all die untimely deaths. "Look you, she loved her kinsman Tybalt dearly, And so did I. Well, we were born to die."
We can see the characterization of Capulet very well in this scene. We know he cares about Juliet; he's making sure she's not married too soon and is asking her permission to marry Paris. But, we also see how unconnected he is with her feelings. She has no desire to marry Paris, and is in fact already in love with Romeo. "Well, Wednesday is too soon. O' Thursday let it be." Capulet is giving her time to grieve.
Capulet says he will talk to Juliet in the morning and that he is sure he will agree to marrying Paris.
