So, lets explore each character one at a time and you decide. Maybe I am the lone wolf here.
Dean stands at around 6'1" and does not have a bad body at all - obviously.
|Dean possessed by a demon|
Sam's eyes are very expressive. While his lips are not as full as Dean's, his smile is off-the-charts (when he does smile).
Sam stands at around 6'4" and has an absolutely ripped body.
