Susan was sensible. It was, she knew, a major character flaw. It did not make you popular, or cheerful, and--this seemed to her to be the most unfair bit--it didn't even make you right.
Susan Sto Helit is Death’s granddaughter. She frequently has to solve a bunch of problems that have been occurring because, for whatever reason, Death decided to take a little vacay. I used Michelle Dockery’s likeness because she played Susan in my favorite holiday film, the Hogfather. Here is Susan wielding deaths second favorite weapon.
What I love about Terry Pratchett's good characters is that they never fail you. Sam Vimes might push you towards the piss puddle for fun, or put a farting pillow under your chair, maybe tie your shoelaces while you're asleep - but he would never fuck your wife or piss into your shoes or make you miserable for no reason other than sheer "fun".
Granny Weatherwax would never say "no" to a crying for help or "please". She wouldn't betray her morals for money, some sort of respect gain or power.
So wouldn't Angua. Or Susan. Or Adora Belle. Or Carrot. Or Luggage.
"Just a minute," said Lobsang. "Who are you? Time has stopped, the world is given over to...fairy tales and monsters, and there's a schoolteacher running around?"
"Best kind of person to have," said Susan. "We don't like silliness. Anyway, I told you...I've inherited certain talents."
"Like living outside time?"
"That's one of them."
"It's a weird talent for a schoolteacher!"
"Good for grading papers, though," said Susan, calmly.
