1) Someone defends Marley.
2) Someone putting Tina in her place.
3) A fic that looks at what a poor job Will does as a teacher. Most of what he does would get him fired in real life. So maybe something about that. Maybe something addressing how he talked to Sam, Blaine, and Unique after the Shooting Star episode. Or how he handled things with Marley.
For all of these fics, I would prefer Klaine (or at least Klaine friendly). So no bashing Blaine or Kurt.
