Isaak saw the look that Verlin sent back to Acacia and he almost rolled his eyes and shook his head but he didn't want to start something. it wasn't because he was afraid, he was just smart in choosing his battles and also he didn't want to get expelled for breaking too many rules. he wasn't expecting the second year's cat to hop onto his lap, and as it purred he gave it a gentle pet. his family had a cat at home as well as an owl, and their cat was very nice to both them and new people who came to their house. when Ester growled at Acacia and Verlin said that it looked like cats didn't like Acacia, he was on the verge a laughing but he stopped himself.

when she asked them about how their summer break went, Isaak replied saying, "It was pretty good, my parents took me and my siblings to see the Quidditch World Cup between Transylvania and Scotland. it was a great game, I was glad to see Scotland win but I was rooting for Transylvania. you should have seen how fast and aggressive some of the chasers were on both teams. but aside from that, I mostly did a bit of practice flying so I could try out for the Slytherin Quidditch team this year, and also some reading on charming spells."

He was glad to have a family that did fun things over the summer, and from the sound of Acacia answer to the question, it looked like she was one of the students who didn't really have the best family life. this made Isaak think of Harry Potter the famous Auror who attended Hogwarts many years ago, he grew up with a terrible aunt and uncle who were muggles since both of his parents were dead. Isaak was glad to have not that sort of misfortune. 

he decided to go get his pet and picked up Ester from his lap and placed the cat beside him. "Excuse me, i going to go get my pet from the storage compartment, I will be back soon."

he got up from his seat and exited the compartment. he walked down the aisle towards the place where students stored to their luggage. he went into the compartment and quickly found the cage that had his ferret. he grabbed the cage and headed back to the compartment with the others, he barely noticed the Hufflepuff Elina, and Willow, but he kept on moving, they were higher years than him so they could probably handle whatever they were doing more than he could. he soon reentered the compartment, and took out his ferret from the cage. he sat back down in his seat and had Perun sit on his lap. "This is my ferret, his name is Perun."
