Gandalf Vs. The Witch King

[Essex]

'Dangerous!' cried Gandalf. 'And so am I, very dangerous: more dangerous than anything you will ever meet, unless you are brought alive before the seat of the Dark Lord.'

Mansun - re your quote from the book above - as I said earlier, does it really PROVE how strong a character is if the character himself says how 'strong' they are? I put it to you that the above is Gandalf's OPINION.

Whereas, for example, the Numenorian blade that Merry used WAS proved to help destroy the Witch King as it was mentioned in the text by the 'narrator'

but to add a further twist to this, can we even trust the 'narrator' of the story, as the LOTR was supposedly handed down from the notes taken by Bilbo / Frodo / Sam after the War of the Ring was completed? What do THEY know of this supernatural blade that was used on the Witch King? - maybe I should delete this last paragraph as it may send as down another cul-de-sac of opinion, denial and arguments...........
