Dean might just be getting used to it, but Jo has spent just over a year - a year - trying to accept it. Trying to understand, and settle in, with the idea that when someone leaves, they go home. And when they go home, they have someone to go home to. But her? The moment she leaves the city, she gone. That's it.

It's easier when she's trying to explain it to someone else. It's easier when she can downplay it outward, act like it doesn't keep her up at night, doesn't leave her trembling a moment longer when she realizes people are gone. What if they're gone for good? What if she'll never see them again? What if, seeing Dean stand in front of her now, is the last thing she ever does?

Not that it would be that different from home (god, she misses her mom sometimes).

Dean steps forward, then, wraps his arms around her for a hug, and Jo tenses. Gale left weeks ago, everyone since then, and while Jo isn't really a physically affectionate person normally, after the initial shock Jo melts into his arms. Her face falls into his chest, and her arms go around his middle, and God, she's missed him. Missed him more than she even realized.
