The levee wasn't the only thing that broke on last night's episode of Supernatural. So did the brotherly bond between Sam and Dean Winchester. As painful as it is to admit, their relationship was torn apart last night and it shows no obvious signs of repair.
The fight over Sam's demon blood addiction has been brewing all season and it finally came to a head in Sam's hotel room. The basic argument is simple: Dean doesn't want his brother to turn into a monster and Sam wants to do everything he can to stop Lilith. Yet those fundamental differences caused the two to have a relatively short fight before Sam walked out the door.
The fight proved one thing - Sam is certainly getting stronger. The fight between the brothers in "Sex and Violence" was a bit more evenly matched, but the one last night lasted all of two seconds before Sam knocked out Dean. But Dean got in the last punch, telling Sam that he never wants to see him again if he leaves. Sam thought about it for a second and left.
The question now becomes: who's right? Do you agree with Sam's position or Dean's? Here's a quick rundown of the two arguments:
Sam's Side: The Greater Good
Sam believes that he must do anything in his power to save the world, even if that means turning into a demon and letting the evil inside him take over. Part of this may stem from feelings of inferiority in the family as Dean was always the older brother, the one who seemed to have more in common with their dad while Sam was the outsider.
The second half of Sam's point is that he doesn't believe in Dean. While the angels have sided with Dean as the one to stop Lucifer from rising, Sam doesn't agree and thinks that Dean is too weak to accomplish the task.
Dean's Side: Brotherly Love
Dean's opinion is equally simple: he loves Sam. He loves Sam more than anything in the world. He already proved that he would willingly go to Hell to save Sam's life and now he's proving that Dean would rather sacrifice the fate of the world than see Sam turn into a monster. That is powerful.
The second part of Dean's position is his belief that he can stop Lilith. This is a secondary disagreement between the brothers. However, even Dean has shown some skepticism around the angels, so it's not clear that he fully believes that even he can stop Lilith. Basically, even Dean would probably admit that Sam's solution for stopping Lilith is 100 percent safe, while his is only about 50/50.
So that's the choice fans now have to make. Is it worth it for Sam to turn into a demon to save the world, or is it worth taking a risk on letting Lucifer rise in order to save Sam's soul? It's certainly not an easy question to answer, which could be the most frustrating point. Both brothers are making good and valid points, so only time (and next week's finale) will tell us whose side is right.
