"It's Oakenshield!" hissed Smaug as he prowled back towards the platform, trying to peer under it so he could see the hobbit hiding beneath. "That filthy little dwarvish usurper! He sent you in here for the Arkenstone, didn't he?"
"No!" protested Bilbo, who had seen the stone just outside where he was hiding, if he inched closer, maybe he could get it... "I don't know what you're talking about!"
"Don't bother denying it!" the dragon snarled, Bilbo jumping and retreating backwards as the dragon's snout and eye suddenly appeared blocking the opening. "I guessed his foul purpose some time ago! But, it matters not, because his quest will fail. There is a darkness coming, and soon it will spread...to every corner of the land!"

"Listen to me carefully," Bard turned to his son. "I need you to distract the guards, once I'm at the top of the tower, I can set the arrow to the bow." he explained.
"There he is!"
"Bard!" the guards suddenly appeared and the two had to run.
"After him! Stop him!" shouted the lead guard.
