That was one of the easier ones for me. I almost missed Jaqen's reappearance though, if I didn't jump to the next book immediately that Pate POV would have been confusing.
That whole Oldtown prologue ending had me confused as hell, until the end of the book when dude calls himself Pate.
Did you catch the Gravedigger/Hound thing? Imma have to re-read them shyts, too much going on
