I agree 100%!! That's how Dean wanted to go out. "Blaze of glory" style, with a machete in his hand. Sam's death was also exactly the way Dean wanted/predicted. While I absolutely agree that we would've been grateful to see Sam and little Dean share some experiences with Baby, the fact that Sam kept her in pristine condition was enough for me. Cause it was their home. I would've expected nothing less. I also kinda wish we could've met Sam's wife, and known how they met, and whatnot. Like, if he had "hit another dog," as Crowley once put it lol.
