Then in yesterday's premiere, Singer was listed in the credits at "Executive Consultant," the title that former showrunner Eric Kripke also held. Producer Jim Michaels confirmed the title change on his twitter today:
The word is that Jeremy Carver now has the title of sole showrunner and will be the main guy in charge, but he'll have help. Phil Sgriccia will also be stepping in with some of the duties that Bob Singer used to take care of (aka the day to day production duties). Whatever the shift, after being with the show on season one, and many years in TV before that, I'm sure this is a welcome change for Singer. It is a crazy, hectic business most of the time. Enjoy the slower pace Mr. Singer, and we're glad you are still remaining close.
