Well we do know that Sun is pregnant, so that may play a more important role now as well. But I think Ben really wants Juliet to gain everyone's trust. The scheme with Claire was meant to let Juliet do something good for one of them, so that she would be more accepted. I think Ben has a bigger plan, once they all trust Juliet. But I think that is the main mission, gain the trust of the survivors.
