A Dance with Dragons
Lord Godric Borrell of Sweetsister tells Davos Seaworth that Lord Triston Sunderland would require him to hand over Davos Seaworth if he was aware that Davos is on Sweetsister.
Godric says Triston would sell Davos to the queen for a pot of Lannister gold; with seven sons all determined to be knights the poor man needs every dragon. Godric has heard Triston bemoaning the cost of destriers and tells Davos it takes a lot of fish to buy a decent suit of plate and mail.
