Susannah's not in District Three, but she's a regular enough visitor there, thanks to Eddie, that she manages to hear about Maximus' military exercise. She doubts she'll be able to take part--not in the chair--but she's been meaning to ask Maximus something and this seems as good a time as any.

Which is why she ends up wheeling herself up to him when she thinks there's a lull in the training. "Excuse me? Mr Maximus?" Or would it be Mr Decimus or Mr Meridus? She hadn't done Latin since high school. "I've been wondering if I could ask you a few things about your leg."

If he looks down he'll be able to see the absence of her own--although if they've met before, he'd probably have noticed then. It's the first thing everyone notices.
