I think that this is so sad. I don't think it was in the movie so I will include it: Even with Jack's arms wrapped around her, Rose is shivering in the cold. Near her a WOMAN with TWO YOUNG DAUGHTERS looks in the eyes of a HUSBAND she knows she may not see agian.

HUSBAND
Goodbye for a little while... only for a little while.
(to his two little girls)
Go with mummy.

The woman stumbles to the boat with the children, hiding her tears from them. Beneath the false good cheer, the man is choked with emotion.

HUSBAND
Hold mummy's hand and be a good girl. That's right.

The ship GROANS and SHUDDERS. The man ahead of Jack is walking like a zombie.

MAN
Yeah, though I walk through the valley of the shadow of death--

JACK
You wanna walk a little faster though that valley, fella?

The CARTMELL FAMILY {my note: the Cartmell family is the family of that little girl, Cora, that Jack was dancing with in the 3rd Class dance party scene} is at the top of a stairwell, jammed agianst a locked gate like Jack and Rose were. Water boils up the stairwell behind them. Bert Cartmell shakes the gate futilely, shouting for help. Little Cora wails as the water boils up around them all.

JACK
We have to move!

He climbs over the stern rail and reaches back for Rose. She is terrified to move. He grabs her hand.

JACK
Come on! I've got you!

Jack pulls her over the rail. It is the same place he pulled her over the rail two nights earlier, going the other direction.
