Haven't seen this mentioned - re 10x8

I too enjoyed discovering Dean's puppy look. But one thing I find interesting about it is that probably the reason we're only seeing it now is that Dean didn't use to get things through that with Sam. He used to tell Sam. He used to argue. Sometimes get worried. Sometimes get lied to or kept out. But not this sort of negotiation. It might be a sign Dean perceives them as more equal now .
