Quietly, now. It's a four day journey to the other side. Let us hope that our presence will go unnoticed.

He's been following us for three days

What then happened to Gollum cannot of course be known for certain. He was peculiarly fitted to survive in such straits, though at the cost of great misery; but he was in great peril of discovery by the servant of Sauron that lurked in Moria, especially since such bare necessity of food as he must have he could only get by thieving dangerously. ... he became lost, and it was a very long time before he found his way about. It thus seems probable that he had not long made his way toward the West-Gate when the Nine Walkers arrived. He knew nothing, of course, about the action of the doors. To him they would seem huge and immovable; and though they had no lock or bar and opened outwards to a thrust, he did not discover that. In any case, he was now far away from any source of food, for the Orcs were mostly in the East End of Moria, and was become weak and desperate, so that even if he had known all about the doors he still could not have thrust them open. It was thus a piece of singular good fortune for Gollum that the Nine Walkers arrived when they did.
