How we cite our quotes: All quotations are from Titanic.
Quote #1
ROSE: It was the ship of dreams to everyone else. To me, it was a slave ship, taking me back to America in chains.
Obviously, this is a pretty over-the-top claim, since she's not being physically confined, whipped, or starved. However, it does speak to how completely trapped and helpless she felt to get out of her engagement to Cal.
Quote #2
ROSE: It was everything. It was my whole world and all the people in it. And the inertia of my life. Plunging ahead and me powerless to stop it.
Rose is trying to explain to Jack why she was miserable enough to consider suicide. Apparently, she feels like she's just kind of being propelled toward a fate she doesn't like without any power to stop herself.
Quote #3
ROSE: I see you had that undertaker of a manservant follow me. How typical.
Cal is fond of having his valet, Lovejoy, follow Rose. Naturally, that kind of thing only contributes to her sense of being trapped.
Quote #4
CAL: My fiancée! Yes, you are! And my wife in practice, if not yet by law, so you will honor me. You will honor me the way a wife is required to honor a husband. Because I will not be made out a fool, Rose. Is this in any way unclear?
When Cal finds out that his prize possession, Rose, has been out frolicking below deck with Jack, he is not pleased. He seems to take it as infidelity, so he throws a huge tantrum with Rose at the breakfast table. When he says that Rose will "honor" him, he basically means obey. Bottom line: Rose's attempt to break free got her in serious trouble.
Quote #5
ROSE: How can you put this on my shoulders?
Ruth is trying to convince Rose not to see Jack anymore, and she's resisting. Rose doesn't understand why the entire future of the family depends on her marital decisions. It all falls on deaf ears, though, since Ruth basically tells her to suck it up.
Quote #6
ROSE: Mr. Andrews, thank God! Where would the Master at Arms take someone under arrest?
Jack gets literally imprisoned right around the time Titanic hits the iceberg. He's handcuffed to a pipe below deck, as water is rushing in.
Quote #7
ROSE: There's no key.
Rose goes to rescue Jack from where he was being detained, since he's certain to drown otherwise, but can't find the right key to the handcuffs that link Jack to a pipe. So, she gets an axe and frees him that way.
Quote #8
TOMMY: For God's sakes, man, there are women and children down here! Let us up so we can have a chance!
In an effort to keep the lifeboat situation under control (and probably to save room for the first-class passengers), the crew had locked the gates from the lower decks to the upper. Tommy Ryan and the others are furious, of course, since locking them below deck is basically condemning them to drowning.
