When Bilbo was wearing the ring and escaped from Gollum, he met goblins at the gate of the mountain. And he should escape from goblins again… But, why did goblins know that Bilbo is at the gate? How did they know?
In my opinion, the reason why goblins knew Bilbo was at the gate is that they foreshadowed Bilbo will try to get out from the mountain. Unfortunately, Bilbo didn’t wear the ring at the gate so he was noticed by one of the goblins. “There is a shadow by the door. Something is outside!”(Page 99) One of the goblins said. He said “something” so we can know that he didn’t know what is outside, but I think they could guess that is Bilbo or Thorin’s company.
