Sounds pretty credible.
For example page two of this article says that Chloe takes a sample of Lucifer's blood from the crime scene to try to find out who he really is, but there are parties who don't want his divinity revealed.
Also, Tom will be singing a "stirring performance" of All Along The Watchtower in the season opener.
