 CONT: In Season 4 Episode 5, Mike Barbosa gets to see Rockys house,  which as seen in Season 2 Episode 3, the front is 2/3 covered with  moss. In Season 4 Episode 10, when filming begins for "Just Two  People", the moss has been stripped away, presumably for the  "filming". The moss is restored by the next episode (Season 5  Episode 1).
