This episode was amazing wtf.
THEY THROWING THE GREATEST HITS AT THEM. Shoutout to the Lilth's actress, She made me think she really watched the season 3 lilith episodes over and over cause she'd completely nailed lilith's talk and tone. I 100% thought it was the same ass lilith from season 3. Which normally isn't the case when demons possess different vessels in this show.
Probably one of the best ending monologues in the history of this show. Dean always has some hero centric speech but this one right here. Dean just look utterly defeated. He's had enough.
"It's God, IT'S GOD SAM, And he's coming for us, How the hell are we gonna fight God"
Knowing where dean started with him not even believing in god to everything up until now. That line hits you right in the feels!!!!!
15 years later and this show can still deliver amazing scenes!!!
Edit
I think they just showed how they are bringing Adam back.
God wants his ending to be "winchester kills winchester" What if they bring Adam back to fill that death? Would probably be the biggest "fukk you" to a television character ever. Imagine spending thousands of year in hell only to come back just meet a narrative in god's story where you die again.
