"He'd been failing them for years."
Yes, so much tragedy attached to Giles' failings. He should have been better able to guide them all; he appeared to have all the right stuff to be a great father figure and mentor to this group of mostly parentless young people: the education, the experience both as Ripper and a proper English gentleman, the good intentions, the compassion and love...and yet, he failed. How can the older generation help the younger, what is their wisdom worth? He took the wrong path, every time. In spite of all the glasses-polishing, he could never really see the truth of the situations. He's doing it again in this story, by misinterpreting Anya's actions. This is such a good story!
