In the new episode "Collaboration," Nandor's (Kayvan Novak) old familiar from the 1970s unexpectedly returns to Staten Island, so a miffed Guillermo (Harvey Guillen) moves out to begin service to a new master, one he hopes will be more appreciative. Elsewhere, Nadja and Laszlo (Natasia Demetriou, Matt Berry) decide to revive their old musical act. Mark Proksch also stars.
