In Titanic, what happened to Rose's mother after the sinking?
I'm curious because she made it very clear while she was lacing up Rose's corset, that she was entirely dependent on Rose's match with Cal to survive. Whether she was exaggerating or not, she made the statement that she would be poor and in the workhouses if not for the marriage and Cal's fortune to support them.
Obviously, since Rose is presumed dead after the sinking, she did not marry Cal and her mother was not able to benefit from his money. So would she then, in fact, end up poor and in the workhouses as she said? Rose didn't just abandon Cal and that lifestyle to start anew, she also had to abandon her mother. So did she leave her mother to be a poor and squandering worker?
At the end of the movie, Rose gives her account of Cal and what happened to him in the following years, but never anything about her mother. I realize this question would probably be more speculation than a factual answer, but I just wondered if there were some clues at the end that I maybe didn't pick up on or if there were some "DVD bonus" or behind the scenes I haven't seen that answered this.
