Eva smiled wider "Alice is her name, she used to be my best friend, though I thought I was just hallucinating all of it." she said with excitement in her voice, shrugging a little "The rest... I have no idea!!".
Alice laughed a little, while looking at them "I guess I'm the best to answer that, eh?" she said, taking a little pirouette while she was speaking. "It's not that other people can't see me, I just chose not to show myself for them." her voice was childish, but the words somehow seemed to belong to a grown up. "And if it's important to know I am Eva's little sister, however nobody knows that I exist, so please don't tell. I was adopted at birth, and no one got knew about it. Now I am a fully qualified witch. They couldn't do that with Eva, I'm afraid, she was already born when they flew, so her existence was impossible to hide." the happy smile on her face was a huge contrast to what she told them. "And now they are coming for you, eh? You guys are in trouble..."
