Bound to Freedom

Tim's pack is an unusual one. His mate, Ari, isn't aware of just how unusual because he's too afraid of being subject to another's will to actually join. When Tony leaves the pack, how far will Gibbs and Tim go to get him back? & when Ziva comes to NCIS, how will Ari react to Tim wanting to turn his long lost sister into a wolf?
