"Her siblings ought to be scared, too."
Lets hope a family member sees Kara as we do, and trys to protect her siblings.
That's what I'm afraid of: that the older brothers will feel like they "have" to take her in. One is a soldier just back from Iraq. The other was bringing his girlfriend home to "meet the parents" at Thanksgiving, apparently in preparation for getting engaged.
How can they handle this situation?
The risk of harm at this point is probably to herself. She turned her back on 2 people that loved her for a man that she is never going to see again.
