Treebeard:
Kransha, because he gives the impression of being around for thousands of years, is full of wit and wisdom, is friendly but will still crush those who oppose him, and is always
hroom-hooming as well.
Faramir:
The Squatter of Amon Rudh, and I'm sorry but I can't quite place this one. It feels right though. (Much like Sam
thought he felt right?)
Bilbo:
Estelyn Telcontar, because she is loved by all wise people and has a wholly unthreatening demeanour.
Eowyn:
Feanor of the Peredhil, possibly because she seems like the kind of girl who could slap you around with some ease.
Galadriel:
Lush, because she's the most famous blonde around.
Haldir:
Nilpaurion Felagund, because it just hit me suddenly as I was typing this that it made perfect sense.
Maybe it's because he looks like an Elf (in my head).
