OH! yes, I remember you saying that about the offhanded way Dean said that line - and I do agree. It's just frustrating that he didn't get it, is all. Dean has talked like that in other episodes too recently (can't remember which...). I am pretty sure this is not the first time. I am imagining it is something that will come up in the "final showdown" again - sort of like Sam going "you don't love me" in the Season 8 finale.
