Has anyone seen http://www.imdb.com/title/tt3196216/fullcredits?ref_=tt_ov_st_sm

Everyone is in this episode:  Partridge, McAllister, Reede, Haffner, KIRKLAND [which must mean his TWIN], Bertram, Minelli -- everyone except Stiles

Also, very curious -- Walter Mashburn returns listed as -- WALTER MASHBURN/RED JOHN

Seriously?  This HAS to be a red herring -- all this time and Heller's not going to let IMDb give it away?
