Apropos of nothing: Some observations and opinions. *g* Five little-known facts about Sam
Sam doesn't just want "a normal life". He wants "a safe and normal life". (Safety comes first in canon and is hardly ever seen in fandom.)
Several years of college do not make you an expert on everything from medieval French poetry to astrophysics. Nor will you have read the entire literary canon of Western civilization, or learned Proto-Indo-European and Sanskrit.
The fact that Sam went to college - and did very well there - does not mean that he is a genius.
Being psychic does not mean you are an altruistic, sensitive, bleeding-hearted angel of compassion. Neither does it mean you are the End of the World.
Sam's Latin pronunciation does not support the idea he is: A. Cicero reborn, or B. any kind of linguistic genius. (In fact, it sucks.) Five little-known facts about Dean
Dean's eyes are green. (I refer to the actor, and the police files to be observed in "Benders", if further evidence is needed.)
Dean is loyal, protective, supportive, and courageous, but his personality does not begin and end with those traits. He is not a dog. Witness the lack of furry ears and the presence of opposable thumbs.
There is no need to emphasize that Dean isn't stupid, because there is no canon indication that he might be. (The fact that Dean built an EMF detector out of a walkman is neither the only nor the most conclusive sign of intelligence on his part.)
Dean is not a misogynist, a chauvinist, or a despoiler of innocence.
From everything we see, Dean genuinely likes and is really good with kids.( Five personal opinions to round it off )
