A Clash of Kings
Because of Weese's abusive nature, Arya Stark gives his name to Jaqen H'ghar. Weese is later found dead, his dog having torn out his throat. While the dog eats parts of his face and ears, someone kills her with a crossbow bolt.
A Feast for Crows
While at the House of Black and White, Arya learns of a paste mixed with basilisk blood which can cause madness in man or beast. Jaqen H'ghar may have fed the paste to the spotted dog before she attacked Weese.
