Sam and Dean Winchester.
He can appear evil at times, especially when he is hooked on demon's blood, but Sam is never evil. Even the power he gains while on demon's blood is used to defeat more powerful demons such as Alistair, and Lilith, and he uses it again in season five to defeat Famine.
Sam and Dean's father is named John Winchester.

He returned on the last supernatural to haunt sam in his dreams as he created illiusions in his mind but saw them happening.
It depends on what you mean. If you mean in Bloody Marry, then his secret about Jessica is that he had dreams of him dieing before it happened and if you go way back to when he first said about him contacting Bloody Marry and you listen to what he says you will understand what this means.
There is a supernatural season six it still includes Sam and Dean my opinion is its the best season yet. one of the episodes includes one of the arc angels trying to pull the plug on earth while same an dean try to stop him in time.
Sam and Dean both use the word ganked quite a bit.
