A) Metro-North passes are EXPENSIVE. A 10-trip pass is either $195 or $125, depending on when you travel. Damn, Quinn. Also, way to set up all the fanfics ever.
B) I refuse to believe that Lima has an Amtrak station. Just no. In fact, no Amtrak trains have stopped in Lima since 1990. Unless Rachel took a trash train or a coal train, she did not travel from Lima to NYC by train.
C) Amtrak trains don’t arrive at Grand Central anyway.
Most of the rest of the episode, though? Okay. I approve of Finn joining the army, I actually won’t hate it if Santana waits a year for Brittany OR if she goes to NY on her own, and Quinn wore a rainbow dress.
