Dean laid silent, unspeaking, watching Cas sleep on the bed next to him. It was the most peaceful thing he could possibly be doing. It was quiet, and he was happy. Small noises began to come from the baby monitor that sat on the nightstand next to Dean's side of the bed. Cas stirred awake, as he always did, but Dean reassured him. "I've got this, Baby. Go back to sleep." Dean got out of bed and walked down the hall, entering the room that had been turned into a little blue nursery. The baby started crying as soon as he walked in, and Dean rushed over to pick him up. "It's okay, Sweetheart, Daddy's got you." Dean took the baby downstairs to the livingroom, being sure to leave off all the lights. He laid down on the couch with the baby on his chest, still fussing. "It's okay. Daddy isn't going to let anything happen to you. The baby continued to fuss. So Dean decided to sing to him. "Carry on my wayward son, there'll be peace when you are done." Cas walked in then, kneeling beside the couch, on hand on Dean's chest, the other stroking the baby's head. They sang together. "Lay your weary head to rest, don't you cry no more." And just like that the baby was asleep. Cas looked at Dean
"You know," Cas said. "The apocalypse, leviathans, the Mark of Cain, the darkness, all of it- this is our peace. Gabriel here is our peace. There really is peace when you are done."
"Gabriel is our peace, and, Cas, you are mine."
