I felt so bad for Cas. He desperately wanted/needed dean to trust him. At no point did Dean try hear Cas tried to tell him. Cas got out all of four words when he first asked Dean to trust him.
Would have been nice to see it played out this way, but IMO, I think it would have played out the same way whether or not the "boys" turned on him or not.
I know but to not even address it. When for example Sam offers to relieve Dean when he is torturing the demon Sam could have brought it up, and Dean could have said something like, I can't let you do that. Or I need you as you are now, I don't need an addict when the shit really hits. Anything. Hell a I can't risk losing you for just two people, or I can't take the chance with your mind blocks, anything. To not address it is a weakness in the script.Mswood, they don't want Sam ganking demons with his mind or on the blood again. He's like an addict that way. I can understand them not going that route. It's not a realistic possibility for them so they don't entertain it. Absolute power corrupts and all that.
It's like if they still had the colt, and kept refusing to use it and never addressed the reason why.
And I still don't see how in the world wiping Lisa & Ben's minds helps them in anyway.
It just keeps them at risk with no avenue for calling anyone for help.
On Sam drinking demon blood, BOTH Dean and Sam himself think Sam is closer to being a monster when he on the "juice" so to speak. So why would they even WANT to mention it? To have him be able to do that he would have to "Detox" time and time again....which in every episode that he did it was extremely painful and dangerous.
As for The Colt, wasn't Ruby I that "helped" Bobby make more bullets? Since she is gone and I am assuming that Bobby doesn't know the entire process. I mean, this was a demon with her priorities for Lucifer to be raised, helping out hunters that will use it to kill demons?
I on the other hand would like it mentioned on just how many bullets are left?
I completely agree with you on Lisa and Ben,...but maybe he realizes how much a distraction they are to his job? But that yet doesn't make sense in itself since Crowley and the demons know he still cares for them.
