After the kidnapping, what happens to the relationships of Lissa, Rose, Christian, and Dimitri?

The rift between Lissa and Rose is completely healed. They are once again best friends. Lissa breaks up with Aaron, and she and Christian start dating. This time, Rose approves of the couple. Rose does not see Dimitri for a while, but finally finds him and confronts him about what happened. Dimitri feels that he has taken advantage of Rose, and that what happened probably would not have happened if she weren't under the spell of Victor's necklace. Rose assures Dimitri that she likes him even without the necklace. Dimitri eventually admits that he likes her too, but that they can not be together. Dimitri must focus on protecting Lissa, and has no time for other relationships.
