Roze winced slightly in sympathy for Dan. She'd never apparated herself - always preferring broom, floo powder, or just muggle transport rather than journey with her Uncle or Brother in that magical way. She'd heard it was awful though - like being stretched and ripped apart and put back together again in a different place. And sometimes splicing happened. Yeuch.
She noticed Dan's brown eyes dimmed slightly - in sadness? Maybe he was just disappointed that he'd missed the first day. She could understand that, she supposed. However, they lit up once more in amazement as he took in her pink hair, and she let out a laugh. His eyes suited happiness better than sadness - they lit up like a rich mahogany fire. 
"Oh, yeah. You'll be seeing a lot of this. I'm a..." she paused, thinking about the term her Uncle had used. "An... em- empathetic met... metamorphus? No, an empathetic metamorphagus! Yeah, one of those. It means that my hair and eye colour changes according to my mood." She said, smiling triumphantly as she remembered the words. Quite the tongue-twister it was. "Pink means I'm amused. Blonde is happy, grey is tired, brown is neutral. It's quite self-explanatory. It means I'm an awful liar though." She said with a sigh, then paused - she'd not mentioned the more negative emotions, and what colours they produced. She didn't like seeing them herself. Changing the subject, she looked at Dan.
"So, whereabouts in America did you move from? I'm assuming you've moved over here for a bit, otherwise you'd be at one of the American Wizarding Schools. I've read a bit about them - I think there's two. Anyways, I hope England is a good substitute for you." She added. His accent hadn't been hard to pick up on - it was fairly prominent, especially among all the British students at Hogwarts. Her Uncle Bobby had an American accent, having spent a few years over there once he'd left the Muggle Army - the Auror's office had sent him to spy or something. He came home when her Mum died (A fact she hadn't mentioned, nor cared to mention to anyone just yet), and stayed in England when her Father was at work, but he was in the States for most of the time. It was only four years ago that he'd begun reporting full-time to the Auror's office situated in London. He'd said it was to mentor her brother, Leo, who had joined the Auror's as soon as leaving Hogwarts - but she could always tell when things became strained in her family, and when they lied to her. Everytime her Uncle visited, she would hear him, her brother and her father discussing things late at night while she was in bed - although never being able to catch a full conversation, the tone was always grim, and words such as 'death' and 'darkness' were often uttered.
