These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Better Than Canon: Special has actually provided plausible explanations for many of the idiosyncrasies of Glee... well, OK, if Glee were also a crossover with Marvel. But still.
Fridge Horror: In-universe example. When all the kids' parents meet up and talk about the memories SHIELD gave them, they start wondering if SHIELD's attempt to prevent the kids from becoming friends and repeating their old relationships (namely Puck/Kurt, Finn/Rachel, Tina/Mike and Brittany/Santana) went so far that they made Puck and Quinn have sex. They're quickly told that nothing of the sort happened.
What an Idiot: Rachel. She's so obsessed with fame she gets Jacob Ben Israel to spread the word about them, despite the fact that she knows there's people out there gunning for them.
Had less to do with fame than desperately wanting some measure of control over her life.
The club runs off to fight bad guys without having a plan or having good control over their powers. They nearly get killed. Repeatedly.
The Woobie: Everyone in the prologue. Notable examples: Quinn, Santana, Kurt and Puck.
At the end of Death and All His Friends, you will want to hug Brittany.
