There were many winding tunnels to traverse on the way to the Farm Gate, where they would pick up horses, camping provisions, and the tracker.  When they passed through one wide gallery, the blue tabard of the City Guard could be glimpsed browsing at one of the shops.  It didn't matter to their mission, of course, but a number of their circle of friends were Guardsmen.<br/><br/>In fact, it was Chay Wytphire in that gallery, and his sharp eyes recognized his friends.  He knew Koh, clearly, and Lulu as a friend, albeit one who resolutely refused to talk about her everyday life with him (much like Koh), but it would have been the greatest surprise to see Cersei.  He was one of the visitors she'd had in her sigil prison cell, and he had no idea why she would be wandering about.  Even if her current company suggested a jailbreak, getting in and out of the Guildhouse was entirely unlikely, so she was most probably out because they let her out, for some reason.<br/><br/>It was such an odd occurrence, he was compelled to investigate.
