1) I think it's a Puck/Kurt but i may be wrong. All I remember is that Kurt broke up with Blaine and Blaine was confused because he had a timetable of their future which included when he would reveal to Kurt that he was a republican and when he would join the log cabin republicans.
2) This may have been a Puck/Kurt one too, but again i'm not sure. The girls (maybe it was Santana?) sent Blaine the song 'best thing you never had' by Beyonce on Kurt's behalf.
To be honest they may be from the same fic, i really don't remember, but i would love to read them again!
