I'm looking for a very vague fic: all I remember is that it happens after the big screaming match in Theatricality and Burt and Carole are on some kind of break.
Something happens to Kurt and for whatever reason, Burt can't accompany him in the ambulance. He calls Carole so she can come pick him up and she comes with Finn. Later I think Burt apologises for calling her althought they are seperated at the moment but Carole just tells him that she would have wanted him to call her anyway.
I'm pretty sure it was a gen fic, but it may be slash (because I read a lot of Puck/Kurt lately)
Does it ring any bells?
