what be and never should be be great insight into the character development of the two main protagonist . i love how the show talk about dean need for family stability while sam and dean relationship be glue by their work while they be so different they complement each other . dean over confidence cause the show trouble and and his duty and honor be his salvation . dean life would be one of trouble if he never have the outlet of hunt . the monster be well do . the end give the reason for the mission and and create round character out of sam and dean . positive . watch the summer rerun . what be and never should be be a fresh and different episode which build depth for the series .
