Someone doesn't HAVE to be present in order to feel a sense of closure with them or the relationship. There are plenty of times that the other party will not, or cannot, be present ... due to death, divorce, or they hate you and don't want to see you again, whatever ... and still you can get closure in your own mind. Bentley is only flown halfway around the world for dramatic effect. At most, they could have set up a Skype, during which Ashley asks him why he really left, or whatever it is she wants to know to achieve closure. He's either going to be honest with her or not, one way or the other. The fact that she needed to see him in person again would upset me if I were one of the other guys.
I mentioned upthread about the Leno show and how strange I found her answer to his question about whether she would go out with him in the real world, knowing what she knows now (AFTER the show ended). Seemed to me her answer indicated that she might.
