Mary had barely let go of John since they returned. Being in the house was a comfort, but being back in his arms let her know she was home in a way nothing else could. She had seen everyone important, from Ben and Dean, to Sam and Heather, and even Ruby, and now she wanted nothing more than to lock herself in the room she shared with her husband and forget about the world outside. It was frightening, to think that somewhere in the city that THING was waiting, likely keeping as close of an eye on the family as the protective elements would allow it.
But John was there, reminding her again that she was safe with that gentle kiss to her temple. She knew that his idea was a good one, that the warm pajamas would feel a lot better than the clothes that she would likely burn because of the reminder of that place...but changing meant letting go of him and she didn't want to. For a moment she ignored his question and rubbed her cheek against his chest. Finally, a long moment later, she pulled back, but not entirely, because her hand grabbed for his and held on almost desperately. She felt silly, not wanting to be alone, but at the moment the only thing keeping her from falling to pieces at the thought of all she had seen and heard was her husband and his familiar strength.
