Posters? I thought all the posters sucked, but nevermind, back to the topic...
Aragorn is probably the staunchest, sternest, and most difficult to read characters in the book. Faramir says that Gollum has closed doors and windows in his mind - he hasn't met Aragorn yet! Keeping true to his point of view, Tolkien lets us know very little of what is in Aragorn's mind. We only really get the story from the hobbits' point of view. The chapters in which Aragorn is separated from the hobbits have a very 3rd person Eye of God feel to them.
Two things which are clear, however:
- Aragorn has no intention of showing any feelings towards Eowyn
- and it pains him to see her hurt by her unrequited love
Rather than a true Love Triangle, I think that Eowyn is the all-too common sad loser on the outside of a happy relationship. But even though she doesn't get the King, she gets the Steward. Loser she may be, but in second place she's the First Loser!
