This guy is understandably furious at Lorent, and is a stone-cold lunatic. He's so determined to "get you" that he managed (with two high-rolls) to get through the grate, slippery as it was with Copper's oil, and follow, but it fell closed behind him, and no one else has made it through yet (in fact, ATM, they are still trying to get the portcullis off the guy that it fell on). He's chasing ON HIS OWN, with little thought to his own safety, other than to take Full Cover after a "cheap shot" with a Firebolt.
