"Remus thinks there might have been some, but I haven't seen any." Well, aside from Severus, but she could never quite make him count as a Death Eater in her mind. Perhaps it was only because they'd been friends and she refused to believe it completely, despite knowing what she did.
His next statement just confused her. Her lips parted as she tried to drum up some sort of protest, because he would never do that, ever, but what did she know about the man he grew into? Still, it made her sad in a way she couldn't really define, because once upon a time, a younger Severus had told her blood didn't matter. Lily wrapped her free arm around her middle and she wondered if she'd ever bring that up to him, or if she'd just forever wonder. It wasn't as though Severus would know, now, about things that happened years into his future, and he could protest all he wanted but why would Dean lie about something like that?
Lost in thought, she barely managed an acknowledging 'of course' to his statement. Maybe she didn't really want to know anything about the war after all. So instead she continued to walk, losing herself in the sounds of their breathing and their shoes against the pavement as she tried so very hard not to speculate how Severus wound up as headmaster, banning Muggle-borns from school.
