When the carriage lurched forward thanks to the stupid beasts pulling it Thomas lost his footing, he fell of the side but was able to grab something before he fell to the ground. He climbed inside. When he saw the lumbering behemouth he pulled out all of his explosive tipped arrows but before he could fire it the sentient armor or whatever it was decimated it to a head and limb. "If that thing can do that by himself why are the rest of us here? It can do this quest on its own." He put back all but one of the explosive tipped arrows, the remained explosive tipped arrow he fired into the mouth of the head/limb freak. The resulting explosion was very satisfying and very disgusting, blood and guts went everywhere.
