I remember they kept it up in high school although Puck and Rachel stayed separated during school hours. I'm pretty sure she called him Noah. The Warblers would come to McKinley and Rachel and Puck would spend the day at Dalton alternately.
Kurt found out when he went to spy on the Warblers and became a part of their group. He did not get along with Finn at all. I think Karofsky still forced Kurt out of school. Rachel and Puck went with him to Dalton (I think Mr. Schue pulled Rachel aside after seeing her with all the Dalton boys and warned her that boys only wanted one thing from her and to stay away from them...or something like that).
Rachel and Puck were Klaine shippers. I remember Rachel telling Kurt he could "totally tap Blainers innocence."
Has anyone run across this story? I loved it and I would like to read it again.
