Tyrion is travelling on a barge with Griff and little Griff, a nun called Lemore who swims naked every day, a husband and wife called Yandry and Ysilla, Duck and Halfmeister Haldon. They have plenty of scones and bacon to eat and spend their days swimming, playing board games, writing a book about dragons, learning foreign languages and maths and history, and admiring the local wildlife. Seems to me they have it pretty good. Why are they risking life and limb venturing into pirate-infested waters on some hair brained quest mostly for Ilyrio's benefit, exactly?
Tyrion is a maltheist: "And when I die, please let them bury me with a crossbow, so I can thank the Father Above for his gifts the same way I thanked the father below."
We learn of the existence of a rare book called "Blood and Fire", which sounds an awful lot like something Melisandre has probably read.
Tyrion thinks Ilyrio sacrificed Viserys. I had assumed that was a bit of a fortunate accident from Ilyrio's point of view, rather than something deliberate.
At the end of the chapter a giant turtle appears, which everyone thinks is good luck. We shall see.
