At the news, Fili walked back to his resting brother, feeling almost sick with dread. If Smaug was to come here, they were done for. All of Laketown would feel the wrath of such a mighty beast; he had heard the stories of Smaug all his life, and he knew about the amount of destruction the Fire-Drake was capable of bringing. If the dragon was coming here, where were the others? Fili couldn't help but worry for their safety; they had headed towards the mountain and Smaug may have met them first. "We need to find Thorin," time was not on their side, since Smaug would arrive within a matter of moments. 

"Get to safety", Bard told them before putting on his coat, taking the Black Arrow, and leaving the house, as quick as he could. He had to get to the windlance, and quickly. However, just as he about a few yards from it, Braga was approaching him. Hiding the arrow in a boat, and covering it, he took off, hoping to evade them, but they were much quicker than him. 

Oin was in full agreement. "We'll need a boat," hastily, he threw his supplies back into his bag, then turned to help Kili who, once again, insisted he was fine. "You'll have to come with us," Saeril explained to Bard's children, but Bane would not hear of it. "Not without our Da--"
"If you stay, you and your sisters will die." She couldn't sugarcoat it, they hadn't a moment to spare. "Is that what your father would want?"

Fili ran to his brother and tried to help him stand, but the youngest again insisted that he can walk. The eldest was ushering Bain, the girls, Yavanna, and the rest of the company quickly to an empty boat that they can use to leave town with. 

Smaug was reaching Laketown, and with a ferocious roar, he let loose a jet of rippling orange flame, catching an entire row of houses alight.
