Arya seems pretty happy selling seafood for Brusco and even has something of a family life in his house. Once a month she visits the temple to give intelligence to the Kindly Man. She meets a sailor whose captain was killed by Salladhor Saan, last seen helping Stannis and Davos, as I remember. She seems to know all the whores in Braavos because they are good customers. The best brothel is Happy Port, where she goes to sell oysters and bumps in to Dareon, with whom she is not impressed for abandoning his vows to the Night's Watch. He is singing about a princess who jumped from a tower because her prince died. I think that sounds like her dad's mistress, Jon Snow's mother. Or possibly I am confused. I remember Arya being told about this by one of Beric's men. GRRM mentions his boots. Dareon mentions Lord Snow being in charge of the watch. Arya doesn't seem to react, but the next thing we know she is delivering boots to Brusco along with the day's profits. It is clear she has killed Dareon. Brutal!
She vistits the temple and chats with The Waif, a mysterious girl who teaches her about poisons. This girl was born the heir of an ancient house but had an evil stepmother who wanted her dead. It is probably possible to identify her from this information but I have not managed it.
Arya tells the kindly man about killing Dareon. He thinks these are the actions of Arya Stark, not the "no one" she is supposed to be now, so he poisons her milk, naturally. I'm assuming the blindness will be temporary.
