Dreamland

The team investigates an apparently inexplicable death by some kind of electricity at a decommissioned airbase, finding themselves teamed with an offbeat character from the Pentagon's elusive, even unheard of, Department 44. Representing Department 44 is Floyd Mayborne who has a habit of appearing out of nowhere seemingly and talking on an invisible cell phone. Mayborne over sees their investigation at the Pentagon’s request but everyone seems unsure what to think about him and his methods. Elsewhere, David ponders his future by going to Don for advice. Alan celebrates his wife’s and Don and Charlie mother’s birthday by giving Amita a heirloom necklace that Margaret asked be given to a daughter-in-law as Alan and she had only boys. Otto Bahnhoff also appears for the first time as they needed an expert on plasma physics and technology.
