As she'd expected. Everyone was going to think their own school was the best. Well, that was fine by Isis, she wasn't going to contradict anyone, just tell them how amazing her school was! "Yes, Ilvermorny! I'm a Thunderbird...we've got four houses, and..." she broken off, surprised. "Rivalry? You mean between the houses? Is that what happens at Hogwarts?" she thought about that for a moment , and then asked "Don't you have a house cup? We have one we have to fill with cranberries, and if we win, we get a party at the end of the year. How could we fill it if we weren't working together?" her voice was genuinely curious, as if the idea of competition had never occurred to her. It had, of course - she'd watched enough quodpot games to enjoy cheering for her own house, but to compete for points was a new concept.
Her thoughts shifted to the grandmother who was an actress, and another difference revealed itself. "I...guess so? Someone who doesn't have any magic, right?" she asked uncertainly. She hadn't realised there would be different words for such simple terms. "I only know my real grandparents on my Dad's side" she added thoughtfully "but Mom's a pureblood, so I guess we don't have any, uh, muggles in our family" Isis shrugged and mae a little grimace, as if having grown up in an entirely magical family was something to apologise for. Truth be told, as excited as she was to be working with Trudy, she hoped her acting skills were good enough.
Besides, they didn't really have any plans for what to do yet. "Yeah...unless...no, that wouldn't work..." she said thoughtfully, and then realising that she hadn't made any sense, explained, giggling "I was going to ask if you knew a spell to make it sound like your voice was coming from another place, and then I remembered that we don't have our wands anyway. We can play different characters, though. Just...like you say, only two of them can be in each scene. So, if we started outside the haunted house, we'd have to be just two people talking about the dare...hmm..." she wondered whether that was going to work and how they could make it appear scary if their audience would need to imagine a ghost.
