It didn't take long for Lianth to come across the fire - though it masked Jack's scent, it was a pretty clear indicator of where he'd been when he started the fire. It would have been far too much of a coincidence for a fire to start just when Jack had run off. Still, this forced Lianth's pursuit to slow down as he had to rely on more physical clues, like footprints, broken branches and general signs of flight that were left behind. The lycanthrope pressed on regardless. Slowed or not, he knew his endurance probably far exceeded Jack's.
