I'm trying to remember what this fic is.
Lindsay gets pregnant - using Brian or Justin's banked sperm - in Canada.
She hides her pregnancy.
She has some sort of mental breakdown around delivery time - maybe she has twins?
Mel is stuck with Lindsay in a mental hospital, baby(ies), Jenny Rebecca and Gus.
Mel and the kids come to Briton, but Mel checks out on the infant(s) - but relocates to Pittsburgh.
I think Lindsay checks out entirely and moves to an artist's colony in Arizona or New Mexico.
This sound familiar to anyone?
