Baby was key tho breh. That's Raylan's endgame. He finally had tangible proof of a life outside of Harlan and something that he values more than his badge. Remember back in season..3 I think, or maybe 4, when Winona told him how he used to do to that poker game every week no matter what happened at the job no matter what his other obligations were. It was something that was important to him and he made time for it. His marriage, as much as he loves Winona, was never enough to keep him away from the job although now they've come to the great place of her being ok with him being devoted to his job but now he's at a place where he finally wants to be devoted to something outside of his job; his daughter and her mom.
