Nimble Dick leads Brienne across the countryside towards the Whispers, a castle where he says he took the Jester. Nimble Dick wins the chapter with his trope-busting no-nonsense advice about magic swords. "The Perfect Knight? The perfect fool he sounds like. What's the point o' having some magic sword if you don't bloody well use it?" Brienne invokes a trope about honour. "Ser Clarence Crabb would have wiped his hairy arse with your Perfect Knight, m'lady. If they'd ever have met, there'd be one more bloody head sitting on the shelf at the Whispers, you ask me. 'I should have used the magic sword,' it'd be saying to all the other heads. 'I should have used the bloody sword.'"
This does Brienne the world of good when she turns up at the castle and it's not Dontos and Sansa but remnants of Vargo Hoat's men. She kills them all with her Valyrian steel sword. Winning the chapter doesn't do Nimble Dick any good: he gets buried.
In other possible trope-busting, the obvious scoundrel turns out to be trustworthy. Or possibly it's more that Brienne didn't give him a chance to run off with all her gold.
Now she thinks that Sansa is at Riverrun. It's actually Arya who was headed for Riverrun. But she didn't get there. Brienne's quest is not going well.
Nimble Dick did make the possibly prescient point that Crack-claw folk are "all good dragons". There may be some useful support for Dany there, when she turns up.
