Author's Note: The storyline between Fargo and Holly is just sad. And I want it to end happy, and I hope it does, but I can't see it happening.
As much as Fargo doesn't want to give up on Holly, he feels like he has to. This is just the latest disaster in one of many that has affected their relationship. Maybe they're just not meant to be.
Holly losing her memory guts him because she won't ever remember the past year. She doesn't love him anymore, doesn't remember dying, none of it. Fargo can't take much more devastation or he'll fall apart at the seams. So that's why he makes the decision that Holly should go home to her parents and never think of him again. Her life was better off without him. And with Eureka being shut down, he doesn't know what to do. For the first time since the timeline changed, he's floundering. It hurts so much. But he has to do what's best for Holly, wants her to be happy. She'll find someone else to fall in love with and won't have to deal with all the fucked up things that have happened in this town. Who would want to? Although he hates the lying, it's the right thing to do in this situation.
Fargo just wishes it didn't feel like he was dying inside.
