I got the feeling that Jensen had a lot of problems with the writing in early season 6 too and didn't feel it was in character for Dean, at least from what he was saying in interviews over the summer before the new season started airing. I always wondered if that was a kneejerk response from Jensen fearing that Dean was going to be written as too soft with a female showrunner, because even the most diehard Dean fans I didn't see arguing that Dean was written OOC or too soft in season 6, and there had been some preparing for the worst after Jensen's interview. I can't remember where I found it now, but I remember being surprised at how dissatisfied Jensen sounded with Dean's characterisation and how he would have to try and put his own spin on it
