I'm enjoying this so so much! You really capture Sam's self-delusional adoration for his brother -- I can really feel him insisting that things are fine just the way they are (as long as Dean stops dating other people). It's so funny and endearing! And I read the Cas interludes as Cas being a caring friend who sees how much they need and love each other -- it feels like Sam's being jealous as a kind of excuse because he can't face his own feelings for Dean. Always with the stomach flutters!!

This is truly awesome -- looking forward to part 2!
