I have to preface this by saying I was stuck with subtitles for the second half so I'm going to have to watch it again. But at least the first part seemed very hinky. Sam just happened to walk to Dean's body in a flowered field a mile from the car where he disappeared? I know these guys are fixated on each other but that was a bit much. If you vanished from the car we were sitting in and then reappeared, I probably would be a bit suspicious about whether you were actually you knowing what these guys know about how wrong things can go. Sam didn't seem too concerned.
Really random stuff---
The cop kid reminded me of the gal that played Eve.
Amara means bitter or sour in Latin and eternal in Greek.
The baby was wearing pink and flowers.
The decor in the 70s house was accurately horrifying. It was missing frogs and mushrooms but had the rest of it.
There was pie on the wall of the mart behind Dean while he was talking with Sam on the phone
Dean, just because the Darkness has a matching tattoo doesn't mean you should go steady with her. Just sayin'.
I'll watch again tomorrow and probably feel differently about it then. I'm going to have to look up the quote about joy in the morning.
