Gibbs regains consciousness, and he says that he remembers "the explosion"; however, he does not recognize or remember Ducky. A neurologist says that Gibbs's organic injuries (his lack of brain damage) are inconsistent with an erasure of 15 years of memory even with a memory of his trauma; the physician suggests that the cause is not a physical one but rather an emotional repression of memory. Gibbs starts to remember a few things; Jen helps, then an old buddy does, then Ziva. Gibbs regains his memory, and he recalls the details of the operation on which he sustained his recent injuries. He figures out the bad guy, gives a severe warning, becomes ignored, then quits.
