In the final Five-O episode, Walter appears only for a few seconds. McGarrett, in the disguise of physics genius and professor Eldon Raintree, has himself captured by his mortal arch-enemy Wo Fat, who, for some crazy reason, cannot see through his disguise. Wo is giving McGarrett a tour of his island hideout and he opens a door to show Walter, who is in charge of communications.
