Here's my own season 3 finale, IMO:
- It should be two-part this time
- It should take place in Washington DC
- Rachel and Finn should not procrastinate their kiss
- The New Directions should make it in the top 10 this time
- Finn needs to wear that same black suit, which he wore in the New York episode.
- Rachel needs to wear that same turquoise dress, which she wore in the New York episode.
- Sam will still not be in these episode, since that character is written out.
