Hi Legate,

OK then, I'll start eliminating my possiblities, probably wrong but...

Aragorn is 'I', Sauron is Withnail, no, sorry, 'He', The One Ring is 'Other', Arwen is 'She'

I'm just the second on His mind - Sauron is very interested in Aragorn
He thought of Other more than of me - but more preoccupied by the Ring

I'm just the second on His mind - especially after the Palantir-ing
Although for me He meant more than She - Tricksy - Sauron meant more than Arwen? Certainly a more immediate concern, but rather un-gallant, no?

Me and Him, so alike We - In a rather not-very-alike way, but I suppose both are great and effective leaders
Touch the same iron, touch the same stone - both touched Anduril, stone, hmm, possibly somewhere in Minas Morgul???

We never speak, We never meet - Yup, (Palantir doesn't count)
What tells you who We are? Our hands alone. - Both have distinctive hands - Sauron has but nine fingers, Aragorn has the hands of a healer.

Not sure I'm convincing myself here!
