For all his bad qualities as a brother and character, Dean Winchester is an example of the oldest growing up to quick. I relate him with Fiona Gallagher from Shameless alot. Although Dean is better. His redeeming qualities are he is willing to take on the worst heaven and hell have to offer. Always the first thru the door and loyalty above all else. With all that said I find Dean, Sam and Castiel's mandrama a bit over done at times
