And their relationships figure into the story exactly how?
There is a reason why middle aged British men wrote stories about men who never really touch or interact with women, but I won't tax your mind by asking you to imagine why.
I was responding to your inaccurate comment that there were no blood-relationships in Book One and gave proof that you were wrong.
Instead of admitting you were wrong you want me to explain each relationship to you and how it figures into the story? LOL.
Are you implying that every man who writes a story about men is gay or something to that effect?
Sam talks about his father and his advice when things get rough. "If my old gaffer could see me now!"
And there isn't anything sweeter than Tom Bombadil and Goldberry's relationship in LoTR.... Going down to the river just to gather lillies for his lady! How romantic!
And Aragorn's entire mission to reclaim the thrown was because his ability to marry Arwen with her father's blessing depended on it.

Your mind is a corrupt place maybe.... But I don't think Tolkien's was.
