Lucy tilted her head a little as she looked at him, but didn't say anything. As far as she remembered, he didn't have any siblings, which ruled out nieces and nephews, but there were any number of other ways Wayne might have a child in his life to be a role model for. A girlfriend who had a child, a new younger sibling, a boyfriend's younger sibling, his own child. Lucy wouldn't assume until she had more information - and if Wayne wanted to tell her by dropping small indirect hints, that was fine too, she could piece them together over time, she didn't need to know everything right away.
"Double glazed or not?" She asked with a shrug, pulling the tap on her can of diet coke before biting into her own sandwich. "I mean, kids break windows with tennis balls and footballs, don't they? They're much softer than a PS2 controller."
As she chewed her mouthful of sandwich, she considered. Wayne was basically the first person to directly ask - but then, if he hadn't been in the magical world he obviously didn't know that she hadn't been there. Still, whatever the reason, this was her first chance to really talk it through. "I'm still deciding, I guess," she admitted, taking a sip of her drink. "I left because I knew I couldn't defend myself well enough, and then I was told I couldn't go back to Hogwarts, so I had to make a life for myself. I got a job, I made friends." She'd felt so good, being able to do things for herself.
"When I got word it was safe again, that I could take seventh year and do my NEWTs..." She made a face. Wayne knew very well just how she'd fared at school work. She'd honestly doubted she would even pass. "It didn't seem worth it." Which sounded cruel, now. Like her friends hadn't been enough reason - but she'd been so tired of always depending on those friends. It had never felt like an equal relationship, except maybe with Wayne.
She glanced at Wayne, not sure how much she wanted to say right now. Because she didn't feel like she belonged in the magical world either. "I know that feeling," she agreed. "But on the other hand, I hate that I have to lie to my muggle friends about six years of my life."
