TV's Best Brothers
#1 Sam and Dean Winchester, Supernatural
Sure, sometimes they fight, and yes one has been chosen by God to defeat Lucifer while the other drinks demon blood, but underneath it all, Sam and Dean love each other because they are the only ones they can depend on. Both of them will do whatever it takes, including giving up their soul, to save the other, and at its core, the brotherly love between these two characters is what makes Supernatural a hit with its fans.
FIX THEM KRIPKE. *weeps*
