Hello all!
I've been looking for this fic forever! It was on fanfiction.net I'm actually worried that it was deleted because I really can't find it! I really hope that's not the case anyway on to the story description:

God commanded Gabriel sleep with Mary to heal her or something so she could have kids, he made her forget they slept together and then later he feels a connection to his grace and realizes it's a connection to Dean.
He sees future him and Dean and Castiel arguing with Michael (s5ep,13 The Song Remains the Same) and realizes Dean is part angel and he's his dad.
John and Mary are still his parents but Gabriel is also his dad.
Then he becomes a part of baby Dean's life in secret until Mary finds out but she's okay with it. Baby Dean has some powers too.It's soo cute how they interact and I really need to find this again!  Oh yeah it might've had Dean/Castiel pairing.

I hope you all can help my poor, miserable, existence by helping me find this story that made me soo happy!

Thanks all in advance!
