1) Kurt gets some kind of redemption.
2) Kurt - mpreg
3) Fics where some portion of any episode is corrected (Kurt or Blaine centered)
4) Really good AU fics featuring Kurt as the main character (ex. read a fic where Blaine was a pirate and Kurt a prince, fic where Kurt is a witch and Blaine is a hunter etc)
Also, please no Blaine bashing. I would prefer completed fics but if the fic is being updated regularly that is okay too.
