Saruman's Ring

Lindil - I take that quote from Saruman as meaning that he beleived Gandalf wished to useurp him as head of the Order

Morfea - I hate to tell you, but it wasn't Saruman that appeared to Aragorn, Legolas and Gimli that night, it was Gandalf. Go back and reread the chapter, you find that Gandalf appears a Second time and they again think he is Saruman...then Gandalf tells them the truth and also tells them that it was him the first time
