Arya, Hot Pie and Gendry are heading north on horses to Riverrun. Hot Pie does not travel well. They assume they are being chased. Eventually they sleep and Arya now gets the benefit of Bran's dream powers. As her wolf she kills their pursuers, so that's handy.
Presumably at some point Arya will meet up with her wolf again.
We don't learn much else. Gendry knows who Arya really is but Hot Pie does not. He's even surprised she can read.
