Wayne Randall's first voyage aboard Supertrain as Harry Flood's second is more than the training run he expected. Flood comes down with mumps (at age 62?) and ends up in isolation. A charity swimsuit fashion show is scheduled in the pool car, meaning Wayne's first meeting with Events Director Penny Whitaker is a hasty hallway hello. Meanwhile, an unseen hand plots to steal an emerald necklace from special guest Zsa Zsa Gabor. Is it special guest Peter Lawford, special guest Lyle Waggoner, or a rando in an obviously fake mustache? And will Wayne, Penny, and Guest Relations Director George Boone (formerly Black Porter) rouse special guest star Abe Vigoda from his dozing in time to catch the thief?

Erik and Justin react to the full retooling of Supertrain. The new central cast gets high marks even if it comes at the expense of the weekly mystery. Erik has a very hard time saying "Lyle Waggoner." Justin recalls a Zsa Zsa Gabor joke long past its freshness dating. The pair remember Weird Baby Man despite him leaving the show a few episodes earlier. Justin loses his mind over Flood's liquified sickbed diet. Peter Lawford's slurred line-readings delight Erik. Zsa Zsa becomes a member of the Istari and Tommy Wiseau makes his way into the discussion.
