Sam was on a hunt with Dean when he had gotten the call that you went into labor at the bunker while Castiel and Gabriel stayed with you.

Sam immediately rushed back, getting there right in time to witness the birth of his daughter. his very first child.

You were a sweating and panting mess when Sam barged into the room.

You were in the middle of crushing Gabriel’s hand as Castiel watched the baby’s progress.

Sam smiled, stopping at your side with a panicked look as he grabbed your hand.
