Parker looked at him with shock. "Seriously? Sister? By now I was expecting anything, literally anything, but only not a sister and a cat." at first he was kinda confused and then he just started to laugh. He understood how strongly Zachariah was attached to his sister and him adressin her as a slimy monster, just made Parker laugh. "That's a good news, I dislike ca-no not cats, rats even on pictures. Little filthy Ratatouille," he shook himself on in disgust, nor was he excited about rats, but he still did it with smile. Something had snapped in him that he was smiling all the time, except when he was frowning, laughing or confused.
"So you're not native? Where are you from then?" he was actually interested in that, not asking just to keep conversation going, it was going pretty well even without them really trying hard to keep it alive. "Yeah, it's really important if you really want to do that. Who would be good at something they hate to do? Nerds only, except if that's not something they just have to do." he was so into music only because he loved that himself, it was totally his choice. If his parents chose his hobby, he would play soccer or basketball. "At this point I'm very happy that Quidditch is something I have already read about, but you know what? I am sure that you will be captain and that you will start journey of wins for your house." he stated with sheepish smile at Zach. He loved to see him so passionated about Quidditch, he already found Zach's soft space. "By the way, if we are talking about Quidditch. Is there any position that has the biggest chance of getting captains badge?" not like he was going to join Slytherin's team, they surely were better without him. He just was interested.
