This is important.
"Find a wife. Makes babies. And when you die and your soul comes to Heaven, find me. Tell me your story."
Castiel has already screwed up Metatron’s original plan. Metatron’s original story involved Cas staying away from the Winchesters, falling in love with a woman, starting a family, having a normal life.
This gif set is focusing on the wrong story. This is an example of what Metatron wanted to happen.
Metatron needed Cas to stay human, to stay away from Heaven, to stay away from the Winchesters.
Cas screwed that up when he chose to steal an angel’s grace in order to help the angels and to help Dean. It always comes back to Cas choosing Dean.
Metatron needed Cas to stay away from Heaven and to stay away from them, because something about Cas in Heaven and being close to Dean is going to unravel the ending of his story.
Cas has a key to the lock on not only Heaven’s gates, but to the power within. I think Dean is the key.
V. interesting though - I wonder IF Metatron IS working hard to keep Dean and Cas apart because there is something specific about them being together that risks destroying his plan…
I’m content simply to believe Metatron really did/does just LIKE Cas and wanted him to have a ‘happy ever after’ story like he said… But it might be cool if there WAS more to it… (although could just be Metatron recognises Dean and Cas make a good team and thus them working together is a threat - what with their team-up history involving taking down Michael and Lucifer and head of the leviathan and all).
