[Galadriel55]

Most of my thoughts have already been mentioned, so instead of repeating I will just make a note about Sam. I think that the Quest really helped him marry, though not in the way it helped Aragorn. Rosie would have married him regardless, that is clear I think - how stoutly she believed in him when he left without a word, how she greeted him, etc. But Sam was too much of a boy still, and it would have taken him much more effort to make the step. The quest gave him more maturity. I'd say that he appreciates his Shire life with Rosie more due to the Quest, but that's more Merry and Pippin than him. He would have appreciated her even without all the adventuring. He's just that kind of person. But he still needed to mature.
