Gandalf blew Galadriel's cover?!

[Lindolirian]

In Dwimordene, in Lorien
Seldom have walked the feet of Men,
Few mortal eyes have seen the light
That lies there ever long and bright.
Galadriel! Galadriel!
Clear is the water of your well;
White is the star in your white hand;
Unmarred, unstained is leaf and land
In Dwimordene, in Lorien
More fair than thoughts of Mortal Men

I can see where it seems that Gandalf mentions Nenya, but you have to remember, only such things are evident to those who bear a Ring of Power themselves. Sam was present when Lady Galadriel showed her Ring to Frodo, but since is is not a Ring-Bearer all he saw was a white star in her white hand. Gandalf must have seen no harm in putting out what many would have thought to be a metaphor for power.

*Edit* Crosspost with Eyrie: Good points... hahaha, it seems we agree.
