“I’m still speculating that Syrio didn’t die. Apart from being a first sword of Braavos, I think he was also one of the faceless men - later showing himself to Arya as Jaquen.”
Outstanding speculation that would explain Jaquen’s concern for Arya.
Yep - I just thought it was too coincidental that a Faceless Man would be in the back of a prisoner cart from the King’s Landing dungeons, shortly after Syrio fought the guards. Yoren was collecting criminals from the dungeon’s to bring to the wall...I can’t imagine Jaquen would have ever been stupid enough to be taken prisoner in the first place.
