There's a scar on her chin that Dean can only see when she's above him, her blonde curls messy and swept back as she arches against him.

He only asks about it once.

He kisses her then and tastes her pain, the paths she's walked, the people she's lost, the maps to where she's been, and all the words she'll never say.
