Pretty Chill for Assimilating Aliens (S4E18)

When Starfleet officers that five years previously were all on the same mission as Geordi start returning to the scene of the crime, disappearing crewmen is suddenly more than just a figure of speech. Now Geordi has to contend with the idea that he too may develop a dreaded case of lobster claw. Can Geordi CSI this mystery before it’s too late? Can’t Worf just put The Club on all the Previa’s steering wheels? Can Data stop reminding everybody that he’s an android? Where were they storing that Clip Show Device? It’s the episode that answers the question, why not Zoidberg?
