About halfway through the film, when Jenny is eating small rectangle-shaped "tea sandwiches," she first bites off the full end of the sandwich, leaving a straight edge. In the next scene, she has only bitten off a corner of the sandwich.
Jenny comes back home from the play to find the door bolted. She previously left the house with her diary in her coat and returns with a program which she throws the way. Later, when Phil discovers her in the rumble seat of his car, the very large "Compendium" book is seen on the back seat, then she is clutching it while talking to his landlord. It is not shown how she got the huge book out of her house, and took nothing else.
