Despite not being a Montague , he hated Capulets. Especially Tybalt.
He's Romeo's best friend for crying out loud!! How couldn't he hate them!! He had to protect and stand with his friends Romeo and Benvolio , and hate the enemy!
After finding out about Romeo's secret relationship with Juliet , a Capulet , he wasn't very pleased. Of course , he was happy for his friend , but a Capulet? Really? Could he not stoop any lower? The day he found out , he vowed he'd never fall in-love with a Capulet. Hell , why fall in-love at all? To him , lust is better than love.
But god , would he prove himself wrong.
One day , he's out and about in the city with Romeo and Benvolio with no care in the world! He's related to the Prince Escalus , and is liked by the Montagues! So why not cause a bit of havoc?
He walks with Romeo and Benvolio towards a billard place , where you have to trade in your guns temporarily to play. And while laughing loudly , and talking at the volume of practically yelling , he noticed her.
In the distance , a gorgeous girl , picking out fruits in the market.
And god , he felt his heart do a flip. Never has he felt like this towards a woman like this. His usual desire of wanting to spend one night with them and move on , replaced by a need to protect and care for this...mystery girl. Not like he'd admit it out loud of course...
