rm | Glee: red herrings, plots that went nowhere, and stuff that made no sense

1. Wasn't Quinn supposed to have some vengeance plotline this episode? Where did that go? Instead she got a haircut? Did she have an actual narrative that was excised so we could get the Klaine and Samcedes post-Nationals stuff?

2. Remember the shooting spoilers from NY, specifically the Tiffany & Co scene with the key and the post-it note and all the ridiculous speculation we engaged in? I could see it in the window when Kurt leads Rachel away from Tiffany, but clearly it wasn't anything. Was it a plotline at one point? Or were the creators just trolling us again?

3. Okay, when Blaine and Kurt have their ILU scene, Blaine says they are on their way to buy sheet music. Blaine is out of uniform and Mercedes says she'll see Kurt later in class. Later, we see Kurt in class in the same outfit he was wearing in the Lima Bean. This raises the following questions:

- While Blaine's out of uniform status can be explained away by the frequently different calendars public and private schools run on, what the fuck sort of schedule do Kurt and Mercedes have that it's a) shocking to run into each other in the middle of the day, b) sheet music stores are open that Kurt and Blaine have time to go to and c) class happens sometimes after that? Can anyone untangle this? ANYONE AT ALL?
