"They're," Lily hesitated, but then he'd find out on his own quickly enough she knew. "Well, they're about my son, actually. I know that is probably very odd for you, and it's even more odd for me. I read them all when I first arrived, but we're all around his life, so - we get talked about of course. Less detail about us since they're more about him and his friends, but we are in them."
And of course there was more detail about Severus than there had been about her because he was actually alive, but Lily didn't talk about that. She didn't really want to drag any of that up right now.
"You do have a potions shop," she said with a smile. "And it's just - there isn't a magical community exactly, but a lot of people who live here in the tower come from worlds where there is magic, albeit not always precisely like ours, and so you have a potions shop and you sell potions to them, and of course some of them still work on others, and people know about you and that you're brilliant at potions, so they like to come and shop there. My son Harry, he actually works there with you, that's who I'm going to tell you won't be in. He can probably take care of things for today while we get clothes and some of these other things sorted out."
Lily stopped and looked over at him in the bathrobe still and remembered she ought to go look for clothes. "Speaking of," she shrugged. "I'll run downstairs and see what the second hand store has in terms of clothing and if they don't have anything I'll be a bit longer, but I'll bring back something."
