I'm not worried about Jared wanting to quit. The CW hasn't renewed anything for next season, not even The Flash, which is about as certain a renewal as you can get. I think they are probably holding out until they know about the Tribune negotiations and/or the Netflix negotiations. If other shows had been renewed and not SPN, I'd be more worried. But I think this is a result of behind the scenes stuff at the CW, not SPN specific. Plus, I think if they knew that one or the other of the Js wasn't resigning they wold announce it.
