Tristan had been used to going to Knockturn Alley, since despite his blood status his mother and father had him live the pureblood life, which meant increased wealth and getting what he wanted. Despite being a half-blood he was still pretty much pureblood.
Even though his older brother was full pureblood, but he still loved his older brother Daniel since he played the role of the older brother vert good for him. Which led to Tristan being his father's puppy and going everywhere his father required him to go. Which led to him having to go to the Betting Shop in Knockturn Alley.
His father and him both shared somewhat of an interest in dark arts, even though he showed it more than his father did. Since his father was an auror and a darn good one. Although his father was quite the unpredictable type of man and he looked and he said.
" Dad do you think we can get any good bets today? " e smirked, since him and his father were both mischievous. Tristan was very much like his father, but he was not one to think he was better than anyone else since he knew he was not.
Then soon his father smiled and he said. " My boy I am sure we will. " he said as he put his hand on the shoulder and patted it. His father and him were inseparable since his father was the only guy he could look up too beside his brother. Then soon he went in the shop and looked around with his father.
