Season 8, Episode 11 - GRAMMAR!!! Elizabeth is the school teacher. Thus, one would expect her to not only know but use correct grammar when speaking.
But no, there she is with little Jack on her lap, both of them covered by a blanket, when she says,"... under this blanket together, nice and cozy and warm, just you and I." Except it should be "just you and ME"! Why? Because the expression is the OBJECT (not the subject) of the sentence. And "me" is objective case, while "I" is subjective! A good "test" is to drop the other person in the sentence and say, "... under this blanket, nice and cozy and warm, just me."
I hear this sort of mistake all the time. Someone once told me that the use of the pronoun "I" when connected to another person, is more "proper"! NO, it is NOT. It is grammatically incorrect if it's the OBJECT of the sentence, not the subject.
When will people, especially script writers, actually LEARN something and use correct grammar in their plays, tv shows and movies? AAARRRGGGH! I learned it when I was a child, and that was a long time ago.
