Man! I have to develop two characters now??
Good questions
Regin. As to what Prim was like -- I honestly hadn't really put any thought into it. As I have announced that she is like Harold, I will leave it to you to decide what she was like, insofar as her character will be defined by his character.
My sense of her, though, is that she was sweet tempered, quiet, thoughtful, and -- given that she loved and lived with Fordogrim -- had the patience of a (extremely patient) saint!
As to Fordogrim's attitude toward Sarah: I'm afraid that he has probably never been too fond of her, but that this has become worse over the years.
And
Witch_Queen: 'ray for Sarah standing up for herself (eventually -- we don't want to rush this: it's a long way to the White Downs).
