The strange dog had a fearsome countenance and made it clear, with plenty of growling and barred teeth, that Ehlissa was to keep her distance. It did not prevent her from following Erac's Cousin at a distance, though -- so that's precisely what she did.
It seemed clear this "cousin" of Erac's planned to lose her in the crowded marketplace, or at least keep them in noisy enough surroundings where he would not be able to hear her from six paces back. So she just talked louder.
"When did you last see your cousin?" she shouted over a vegetable cart.
"When I was facing him."
"Was this recently?" She struggled to keep close as the dog nipped at her.
"Recently enough," Erac's Cousin answered, peeking back around a pair of merchants whispering to each other.
"Did he say where he was going?" she asked, hoping to see if this man even knew of Erac's trip to Castle Greyhawk.
