>> I think I read a similar opinion about maturity within a group in one of Viridian's author's notes
I knew that sounded familiar as I was typing it. I don't know whether
I had the idea before he put it into my head or not, but now it's
there and I think it's true.
>> I don't think there's any evidence of this in canon
Perhaps not directly, but it's not much of a stretch in my opinion. We
know canon Ron has an inferiority complex. We know he has an
overprotective streak a mile long with regards to his sister. While in
canon he's pretty materialistic about it, we know that Ron is aware
that - to be perfectly honest - he doesn't have a lot to offer his
friends other than himself. As in, he's got no money; he's got no neat
toys; he hasn't got an overabundance of brainpower or academic
prowess. I'm not saying he is worthless, I'm just saying that with the
slightest bit of maturity Ron might very well realize that what he
does have to offer people is the way he can act toward them -
especially anyone smaller than him, since he does have physical size
going for him. I think this is why in many fanfics, one of three
things happens to Ron. 1 - he is vilified to a large extent - H/Hr
lovers like this one; 2 - he is ignored or otherwise highly minimized
- H/G purists abound!; 3 - those protective aspects of his nature are
embellished and brought out, generally in a more rounded fic.
Obviously I've not read all available fanfics out there, but those are
my general observations.
Also, from my observations of Ron in a mixture of canon, your
fanfiction, and others where they don't ignore him or turn him into an
annoyance or bad guy, I think that another reason he would pick
Hermione is that in addition to liking her he feels she needs the
protection. This is not to say that he would ever want to place
himself in a duel with her or anything; what I mean is that Hermione
*does* need someone to protect her - mostly from herself. In canon,
good examples of this would again be SPEW, but also Hermione's naive
early interactions with Rita Skeeter as well as her blind acceptance
of authority. One might also make a good argument for her not being a
particularly good judge of character: aside from Lockhart, she also
managed to thoroughly ignore Harry in HBP with regards to Draco, and
more-or-less held unwavering, if reluctant, trust in Snape. Regardless
of whether Snape ended up on the side of the light or the dark during
the final reckoning, no sane person can make an argument for him being
a *good* guy, and he definitely didn't engender trust in those around
him, but there Hermione was. Not that she would accept it, but
Hermione would do well to have a miniature Ron sitting on her shoulder
(or a full sized one whispering into her ear - take your pick)
pointing out the things that are obvious to others but invisible to
her. He wouldn't need to do it very often, but if she would listen
when Ron (or whoever, really, just Ron is really the only one jumping
for the job) makes a suggestion like that she would truly save herself
a lot of grief. Now, the obvious exception to this being that she's
not allowed to take boy advice from Ron, since even she knows that
would be a bit biased. :)
