I am, however, surprised that all the fic pairing labels I've seen for this fandom are all Arthur/Eames when I have now learned that Leonardo DiCaprio's character is named neither of those. Nor is Cillian Murphy's, nor Ken Watanabe's. Though I get why--those two are characters who particularly invite you to speculate on their origins and fates. But I still think I would write Cobb/Saito or Cobb/Fischer if I wrote anything.
I cannot believe that I watch fandomsecrets and still managed to stay completely unspoiled for this movie. Serious paranoia scrolling worked.
