A few months ago, Miles probably wouldn't have understood what Cass meant by that statement - being the selfish bastard that he had been, but he had a wife - children - now, and the fact that his thoughts were now more concerned about what was going to happen to them if anything happened to him. He simply nodded in understanding, not sure any words now would sound anything other than trite.
He watched as Cass swiped the bottle, and he was more than happy to let him have it. Hell, he had a crate of it under the desk, and Cass was welcome to the lot of it. "No, no it doesn't help." It wouldn't help anyone but himself, and he was totally doing it to assuage his own guilt.
"If you tell anyone else, they'll find out too. They bloody well seem to know everything." Someone in Cass' family was going to end up getting hurt - either Cass, or his mother - and the more who got involved, the more who seemed to fall under the Lestrange's thumb. Just look at Daphne. Married to him less than six months, and they had already made her an accomplice, and her parents were virtually held at wandpoint, their home taken over.
