"Psychic?!" Lily's eyes widened and she laughed. "My oldest brother might claim to be psychic, but he's really not. I think I would actually go a bit mad if any of them were." She had to smile though, her love for her family clear on her face. "Wouldn't trade any of them at all. Love them to bits, annoying habits and all."
She brightened with interest at hearing Iliana was a witch too. "Magic definitely helps here, and maybe it will help when you're sent home too. I'm not totally sure how that bit works, but I think it makes sense." As much as anything with the Seal ever made sense. Lily had sort of adjusted to the idea that the world she was in was crazy, even by wizard standards, and it was best to just go with it.
"I'm a witch too, which you probably guessed already, the whole Apparating you here thing and all." She drew out her wand, waving it to make some small sparks appear. "It runs in families in my world. Some people are just born with magic, and our school helps us train."
Of course, it was both easier and harder to explain, what with the whole fictional thing. "I don't suppose you've ever heard of Harry Potter, have you?"
