In "Ghosts", we have a very intriguing and sad episode focusing on Admiral Chegwidden when he was a SEAL lieutenant in Vietnam. Tragic events that take place throughout the episode are a nice way to show a softer side to the hard-nosed irascible admiral, who generally spends his time growling at Harm and Mac and co. Right to the end, I wasn't quite sure where the threat to Chegwidden was coming from, so kudos for the writers for keeping us - or, at least, me - guessing. Steven Culp has another maxi-cameo as CIA agent Clayton Webb, and Boris Yeltsin features as well! John M. Jackson does a great job displaying the admiral's grief - very believable.
