I like the concept of this, though I think you could have captured the shock value quite a bit better. I mean, imagine your friend who had been dead for years pretty much coming back from the dead. I think Gibbs would have been plain pissed at her for not telling him (basically lying to him) and the other characters would have had to bombard her with questions before they accepted her back. They may even have had to take time to accept her back (after all, their lives would have moved on too) Anyways, I really do like the concept and how it played out, but I think you easily could have made this a ton longer and ended with the same result :)
