The teaser for this episode was which one would break up. Spoiler alert!
The answer was they all did, pretty much.
But the episode itself was very well written and focused on the characters, albeit most of the time was spent in NYC. Suspending reality a few minutes prevented a perfect 10: Finn's gun would never have been loaded while he cleaned it, and where did he get the money to just jet back and forth to NY if he hasn't worked for months? Anyway...
All the musical numbers worked seamlessly with the script. The final number was phenomenal. While not a lot of time was spent in Ohio (which was fine since a lot of time was spent on the nasty cheerleader) I hope they keep this up. Time will tell.
