Private to Potter
Potter, I take it you're aware of the recent appearance of Draco's son. I've run tests and he's definitely Draco's, but I'm at a loss as to how he came to be. There are no memory charms in place on either of them. Since I was away, I have no idea who was around Draco before he came here. The child says his mother is Astoria Greengrass. Did you know her or have any interactions with her?
