Answer:
Lord Capulet offers the most hope that the feud between the Capulet's and Montague's could end. In the scene where Romeo and Juliet meet, the Montague's were not to attend the party, but Romeo wanted to see Rosaline, his lost love. At the party Romeo is spotted by Tybalt who reports to Lord Capulet about his findings. To this Lord Capulet says,
"Content thee, gentle coz. Let him alone.
He bears him like a portly gentleman,
And, to say truth, Verona brags of him
To be a virtuous and well-governed youth.
I would not for the wealth of all the town
Here in my house do him disparagement.
Therefore be patient. Take no note of him.
It is my will, the which if thou respect,
Show a fair presence and put off these frowns,
An ill-beseeming semblance for a feast."
With his calmness toward Romeo, it gives the reader hope that the feud could potentially come to an end.
