Karen's Note: This was one of those episodes where I found it extremely difficult to keep my most memorable moments down to a reasonable minimum. From start to finish, this episode was not only the best of everything, it was also so intertwined.
Best Broment
It was difficult to pick one moment as all the scenes between the brothers were pretty much Bro-moments, however, I'm going with a string of moments, starting with ....

Sam being over taken by the fog

Telling Dean to stay back

Dean going to his brother despite the risks

Sam losing faith due to the fogs effects..."You're gonna chose Amara over me"

Dean demanding God to "Stop this! You hear me you dick!"

Dean hanging on to Sam as he slowly succumbs

A sudden glow in Sam's pocket emerges

It is Dean's amulet

The surprised look on Dean's face when he finds out that Sam had it all this time and that it's glowing

Sam's look of being found out and that it's glowing.
