That was not the ending I was expecting. I was kind of sad at the thought of Gwen, Lance and everyone not being part of Isabel's life anymore, but I was just expecting her to get Arthur in her time.
I was really worried about Gwen being 'vapid'. I'm glad that wasn't really the case. I do wonder if there was an age difference between Gwen and Arthur. I'm betting so, since Gwen seemed so much younger than Arthur, like a ten year or so age difference. That could, of course, be completely wrong.
