"W-Woaahhh!" Kili shouted out loud, all the jumping and dangling off the branches that the Wargs were doing had actually begun to pull the trees up by their roots, and soon (one by one), the trees all collapsed until Gandalf and all the dwarves were huddled in one of the trees, which had fallen vertically and dangled off the edge of the cliff.

Ori screamed as he too lost his grip, and as Dori lunged to try and rescue him he fell too, if it hadn't been for Gandalf sticking out his staff for Dori to grab both the dwarves would have fallen to their deaths. Dori now had a feeble grip on the wizard's staff while Ori clung to his ankle, whimpering.

It was then that Azog himself appeared with two more Orcs at either side of him, and Thorin had to stare at the Pale Orc in utter disbelief. 
"Azog..." he breathed, unable to say anything else.
"Do you smell that?" Azog sneered as he sniffed the air. "The scent of fear." he looked up at the dwarven prince with malice in his eyes. "I remember your father reeked of it, Thorin son of Thrain."
