Blandings, for sure check out "Everything Old is New Again" by Lula Bo. It's on fanfiction.net, it's over 10 years old but it has by far the best Marty/Rory relationship - it's about all 3 Gilmore women but each has their own chapters so you can kind of skip to the Rory parts if you want. It's SO GOOD. I still read it every once in a while! It's what I wish happened instead of the weird turn they took with Marty's character.
