Nola Rice: Men think I may be something special.
Chris Wilton: Are you?
Nola Rice: No one's ever asked for their money back.
Nola Rice: You're going to do very well for yourself. Unless you blow it.
Chris Wilton: And how am I going to blow it?
Nola Rice: By making a pass at me.
Continuity mistake: When Chris finds Nola in the Tate Modern Museum, her arm changes from bent to down between front and back shots.
Question: Is Nola really pregnant? She's taking medicine and the police say nothing about a pregnancy to Chris, when they show him Nola's diary.
Answer: Yes, she was pregnant. At the end, Mrs. Eastby's ghost confronts Chris about killing his unborn child by murdering Nola. This was intended as a literary plot device known as "exposition." It tells the audience that Nola was pregnant and that Chris, by his response, knew it was true, making his crime even more heinous.
Mrs. Eastby's ghost could just as easily be conjured up by Chris's own mind, which means that "she" wouldn't know anything that Chris wouldn't know. If you're going to be snarky, it helps to have thought through the possibilities a bit better.
Answer: No, she's not pregnant.
Wasn't there a clip of her with a positive pregnancy test? But in saying that, surely she would have written about it in her diary, and it would have shown up on her autopsy.
