It seems every time I have convinced myself that all this with Peter Morgan is nothing, he or other things pops that makes me doubt again. What is he some kind of dark wizard or what?

Lol! Seems like he is, indeed.
I don’t know, anon. That girl is probably not the only child who have a parent who works with Gillian and that Piper follows. They don’t live in the same city, the only thing we know is that their parents, who seem to navigate in the same circles a lot lately, tend to bring these girls as their date to parties and events. So maybe that happened and that’s how they met. Or maybe it’s something else. PM have four other kids, some are also on IG, and they’re not following Piper and Piper isn’t following them. So there’s that.
I’d rather focus on the adults, though, and the joy of tonight double event 🙄
