I saw the first epiosode of Friends ("The One Where Monica Gets a Roommate") and there's a discussion about Ross and Carol splitting up because she's a lesbian. Ross says that he told his parents and they seemed to take it pretty well. Monica then says that she got a call from their mother
Ross: I told mom and dad last night, they seemed to take it pretty well.
Monica: Oh really, so that hysterical phone call I got from a woman at sobbing 3:00 A.M., "I'll never have grandchildren, I'll never have grandchildren." was what? A wrong number?
I was wondering what exactly Ross told his parents - only that he and Carol split up or that she's a lesbian. I figured that "I'll never have grandchildren" was Mrs Geller freaking out because her daughter in law is a lesbian and that would mean she won't get pregnant (by Ross).
But then in the very next episode the Gellers are having dinner and:
Ross: Okay! Okay. (To his parents) Look, I, uh- I realise you guys have been wondering what exactly happened between Carol and me, and, so, well, here's the deal. Carol's a lesbian. She's living with a woman named Susan. She's pregnant with my child, and she and Susan are going to raise the baby.
(Stunned silence ensues.)
Mrs. Geller: (To Monica) And you knew about this?!
and that means she only founds out about the lesbian thing now.
"Friends" have a lot of plot holes so was this yet another one or am I missing something?
