Gandalf:
Frodo, come and help an old man. How's your shoulder?

Frodo:
Better than it was.

Gandalf:
And the Ring? You feel its power growing, don't you? I've felt it too. You must be careful now. Evil will be drawn to you from outside the Fellowship... and, I fear, from within.

Frodo:
Who then, do I trust?

Gandalf:
You must trust yourself. Trust your own strengths.

Frodo:
What do you mean?

Gandalf:
There are many powers in this world, for good or for evil. Some are greater than I am. And against some, I have not yet been tested.
