The Truth About Sam And Dean Winchester's Relationship In Supernatural

Sam and Dean have plenty of arguments that drive them apart, but in the end they always come back to each other. Of course, that's exactly how Supernatural ends.

The series culminates in a completely meta storyline in which they discover that God has been running the show since forever in an effort to make an interesting story. God takes on the role of Supernatural's writers, as he's blamed for putting them through every horrible hardship they've faced for their entire lives. Well, once they finally take away God's power, Dean no longer has plot armor, and thus dies like a normal hunter would — in a tiff with a couple of vampires. He tells Sam to let him go, and their cycle of valiant self-destruction finally comes to an end.

Sam, meanwhile, goes on to live his relatively normal life, and names his son after Dean. However, when Sam finally dies of old age, he's reunited with his brother in Heaven. They're back together again; this time, forever.
