Rebekah was a Mikealson, she was strong and she was determined, not be cattled like the rest of the women in Westros, she would not be bought and sold by men for their amusement - given half a chance she would play all of them. The only daughter of a powerful house, she knew deep down that this was unlikely she would ever be free to marry whomever she wished but the elder she got without being married, the more she was able to convince herself that she would not be forced into some loveless union.
Sometimes she wished she had born a Wildling, she wouldn't have to obey rules, she would be a free woman. She would never speak of this desire though, perhaps occasionally she would confine an offhand remark to her beloved brother, Niklaus, but she knew she should never speak such words in a serious manner. So Rebekah did what was expected of her, she wore the dresses, did her hair, curtsied and cooed whenever was appropriate - she was a lady even if she did not want to be.
But now she had far more important concerns then marriage and dresses; a war was looming on the horizon and her family had now placed themselves in the midst of it all, not that she had a great deal to worry about, none would go up against her family and succeed, she was assured of that. But still, war was inconvenient to say the least and down right boring on the other hand; Rebekah was sure she would be more able than most of the men that would fight on their side but she would never get the chance, she would be locked away, coddled. It was all very frustrating. But still, beneath the confidence she always spoke with, Rebekah was worried, worried about her brothers. War was war, there was never any guarantee that they would return unharmed or even at all, and then there was Henrick, growing sicker and sicker by the day.
Whilst Rebekah did occasionally dream of becoming a Wildling, she would never choose that life - not when she had her family. Family Above All, of course
