Here was what I wanted for Finchel:
1. Nobody from McKinley got into NYADA
2. Finn got no football scholarship and failed to get into PACE.
3. Facing the prospect of both of them ending up Lima Losers, they pack up Finns truck and just drive to NYC.
4. They find that shoebox apartment and land lowly jobs: Finn a mechanic or tire guy; Rachel a waitress in an outer-borough restaurant
5. Rachel auditions but fails to land anything, so they both decide to study music at a different school. Queens College, perhaps.
6. In the meantime, they form a band with some classmates (called "Finchel", natch)
7. Write songs together and live rich happy lives with nothing handed to them.
8. If Finn dies, so be it. At least he died living a dignified life. And Rachel can struggle on, paying her dues until eventually achieving her dreams.
