[after Dean confronts Sam about using his powers
You were gone. I was here. I had to keep on fighting without you. And what I'm doing, it works.
Tell me, if it's so terrific, then why'd you lie about it to me? Why did an angel tell me to stop you?
[Sam looks up, startled at Dean
Cas said if I don't stop you, he will. See what that means, Sam? That means that *God* doesn't want you doing this. So, are you just gonna stand there and tell me that everything is all good?
