Quote smallworld: The only one Ian cares about is himself. He is a scoundrel, and will marry the girl to protect himself from prosecution, and to extort money from the Newman's. Remember he is a master manipulator, and will say anything to get his way. I would go as far as to say, he may be holding her hostage, and forcing her into marriage.
You make a lot of sense. At first they made it look like she and Kevin were going to run off together but that didn't happen. I wonder if Kevin is going to play some part in her return. At work he was told to help find Ian and Mariah. At first I didn't like this story but it is holding my interest now.
