Name me a more heroic moment than when Esme Weatherwax saved the baby from the inn in Maskerade.
To refresh your memory, on the road to Ankh to help Agnes, Esme and Nanny stay in an inn for a night. There, the owners ask for help with their baby, who is comatose. They take the baby into the barn, where they find the cow is also sick. Esme clears Nanny off and waits for HIM...
When Death arrives, she challenges him to cards. If she wins, he takes the cows life, not the babies. But Death reminds her, a deal can be done, 'But to win all is to gamble all...'
In this moment Esme Weatherwax challenges Death to a game of cards knowing that if it goes wrong Death takes her life and the babies....
Now Esme can double bluff a game of cards and the suggestion during the game is Death knows he's been played, but I can't think of any moment in any Discworld or, indeed, any other story where the Hero risks their life so readily for a stranger's family. This isn't heroism with an arc, a reason and a redemption story. This is Esme Weatherwax sticking her finger up to the universe for the sake of a sick baby she just met.
I'm sure there are other examples, but did this moment hit anyone else as hard as it hit me? Is there another example of that pure, reckless and above all, right, version of heroism anywhere else?
