Hmm, that part about the children not being registered for any magic school is mysterious. I wonder how they managed to remain hidden.
McGonagall is taking quite a risk going to meet him like that. The whole thing COULD be a trap. I don't think it is, but she has no way of knowing if the letter is from who she thinks it is and there are plenty of people with a grudge against her.
I think Ginny is being pretty unfair to Albus. He is not responsible for what James does. And as he pointed out, he probably COULDN'T have done so anyway.
In fact, it sounds as if he hasn't been treated too well in general. I know his family can't help not having anything in common with him, but it doesn't sound as if they've made much effort to share his interests. Something as minor as the house you are placed in at school shouldn't have any affect on your relationship with your parents and Harry and Ginny ought to have made sure Albus knew that.
Of course some people just DO prefer their own company and there's nothing wrong with that but it sounds like there's a little bit more to this.
At least Ginny seems to be concerned about him, but she doesn't seem to be DOING much.
Harry does have a point that the Weasley family for the most part are rather outgoing, sporty, talkative people, so being quiet seems out of place and doesn't necessarily mean there is something wrong.
This story sounds intriguing in a number of ways - what is going on with Albus, how those kids were hidden, who this Sartorius is.
Author's Response: Thanks so much for reading my chapter. I can't say much as I didn't want to ruin anything. But you are on the right track. I am really surprised and grateful that someone is able to pick up on so many things that I am trying to express, as it took a lot of research and hard work to produce this chapter. Keep reading and have a great day.
