Well if the shout hadn't made him duck the fireball passing uncomfortably close to his head certainly did. One Treant went up in flames immediately at the attack and two others who'd been struck by the sparks were now advancing on her, clearly bent on avenging their fallen brethren, and the previously calm Ziz were also squawking aggressively in her direction. And after that the woman had the nerve to shout nonsense and then ask him if he was going to lead her somewhere?

Foulques straightened back to his full height, glaring daggers at the woman. "Are you mad?!", he half shouted. "You're like to set the whole forest ablaze and draw the ire of every beast for malms around, you swifting imbecile! I'll not lead you anywhere!" In fact he was backing away rather quickly so as not to get caught up in the battle she'd incited with the Treants and Ziz. Normally he could slay either with little trouble, but he was currently weaponless and misliked his chances without a spear in hand.
