Aiden frowned. 'What do you mean by being together?' he asked, because it didn't sound like Percy was talking about playing together or spending time together. If he did then he was strange because how could someone mind that?
There was something else that bothered him too, and he looked at Cass as Percy said he went after the most dangerous wizards. 'So he gets in danger lots?' Aiden asked, not sure if he liked that. He knew what danger meant, Nana had taught him that if he did dangerous things he might get hurt or even die, and then she'd died, though he didn't know that she had done something dangerous.
'Does that mean that you're going to die?' he asked Cass, tilting his head. 'What happens when you die?' he then tagged on. Mum had said that you just went away and didn't exist any more but that seemed strange because you couldn't just vanish. He wondered if Cass or Percy knew where you went when you died.
