I'm hoping I'm wrong about the Cas/Jack bond taking away from the Sam/Jack bond. It's just that we have been burned so many times by having no one bond specifically with Sam. One of the few ways things got better last season was having both Rowena and Jack bond with Sam, instead of "everybody loves Dean". I'm just nervous about the whole thing, especially since last year they said Sam will kill Rowena. I just worry they are going to take everything, except Dean, away from him again. And that would suck.
