Quote 1
"Do you imagine—" Mr. Lorry had begun, when Miss Pross took him up short with:
"Never imagine anything. Have no imagination at all." (2.6.54-5)
Miss Pross attributes her unquestioning loyalty to Lucie to her lack of imagination: she doesn’t have to imagine how Lucie or Doctor Manette would feel, she just does what she can to shield them from the rest of the world.
Quote 2
"[…] the short and the long of it is, that I am a subject of His Most Gracious Majesty King George the Third"; Miss Pross curtseyed at the name; "and as such, my maxim is, Confound their politics, Frustrate their knavish tricks, On him our hopes we fix, God save the King!" (3.7.18)
Miss Pross’s sudden jump into a mantra upholding the English monarchy demonstrates a kind of unthinking loyalty that Dickens might just be mocking.
Quote 3
"I am desperate. I don't care an English Twopence for myself. I know that the longer I keep you here, the greater hope there is for my Ladybird." (3.14.85)
Miss Pross faces off with Madame Defarge, an interesting sidestepping of the supposedly inevitable confrontation of the two female centers of the novel: Lucie and Madame Defarge. Why does Lucie manage to miss out on all of the climactic moments of the novel?
