Speaking of Sally-Anne, this is the first instance of her playing an oculist:

And then on the potato farm there was a man who'd lost an eye, he
wanted me to re-grow it for him but I knew I couldn't do that. I don't
know if even grown-up wizards can do that but I don't think there's a
spell for it. The socket was all bare and horrible looking and he said
what really bothered him was how it looked and if I could possibly
make him an artificial eye that would be good enough. So I took a
glass marble, and I made it bigger, and then I tried the colourchanging
charm to make it look like an eye. And I don't know why it
won't work on my clothing I got from the Strettons, it's all still grey,
but it worked perfectly on the eye, I got it to match his other eye and
everything. He popped it in and looked in a mirror and said it was
perfect.

Did you remember that and use it to come up with her later internship opportunity, or was that something you went back and found and decided to use, or was it just a coincidence?
