They definitely took steps to put her in the running, so to speak.
She was supposed to go to Edinburgh and she transferred to St A's once it was announced he was going there.
He did a gap year/placement thing, she tried to get on to exactly the same one but couldn't.
I do believe the stories from girls she went to school with, that she fancied him and had posters on her wall. As much as she might try to deny it, because it's embarrassing!
Of course the mother couldn't engineer the entire relationship, but I think Kate was strategically placed for it to be a possibility and it worked!
