'I know for a fact, though, that Antonin understands all to well that innocent victims were not acceptable as collateral damage. I looked into his background when he first came to town, before I even met him. Before he even joined the Death Eaters, his mother and sisters were visiting friends her in England and killed by members of the Order of the Phoenix for being in the house of a family suspected of being Death Eaters. He served time in Azkaban for avenging his family, but he did that after formally challenging them to a duel. He left the Death Eaters when Voldemort dishonorably chose to target children. But I can assure you that he does not consider the harm done to innocent people as acceptable!'
'And he doesn't condone random killing based solely on suspicion, either. If he hears that Hepzibah down the street might be a Death Eater, he wouldn't tell you to go out and kill her. Now, he's not going to hold back if someone is trying to kill him or some other innocent party. And he's not going to expend extra time to 'bag and tag' this Death Eater on a battlefield when it gives that one over there ample time and opportunity to kill five other people while he's doing it. Neither would I.'
'And there are a number of wizards and others who have given ample evidence of their reprehensible and evil nature that I'm not going to cry over when they turn up dead and that it wouldn't bother me in the least to help along their way. Percy and I disagree about that. Or rather, we disagree about the 'method' of helping them on their way. But if I meet Fenrir Greyback or one of the Lestranges at a point where I have means and opportunity, then I would use it.'
'I'm not asking you to agree with it. And I'm not planning asking you to work toward that end. My idea is for you to do the same sort of job you've been doing for the Aurors so we can pass the information along to Percy. You cannot identify yourself as an Auror, but frankly, there are places Aurors can't go and information that they don't hear, and that's where you come in. I'll leave it to you and Percy to work out what is acceptable and what boundaries you may not cross that would interfere with the job the Aurors do. I promised Percy that you would not be involved in anything that wouldn't hold up under scrutiny.'
She didn't mention that the last bit had more to do with his connection to Percy and than her desire to work within the constraints of the law. In her opinion, she just interpreted gray areas of the law in a different way than Percy, but she would let Cass use Percy's interpretation for the sake of their relationship. She had promised, after all.
'Actually,' she mused with a frown, 'I think I promised that anything any of us did would hold up under scrutiny, too.' She scratched her head. She was pretty sure that was the way Percy would see it. Certainly, if she asked him now, that's what he would say that she'd promised.
