The scar below Natasha's right ear is her only scar. She had had many fatal wounds but made sure to tend to them or quickly be rid of the marks that they made. She didn't want to be constantly reminded of the things she did to earn them. But her one scar, she keeps as a companion. A trophy. It's small, less than an inch. It holds the memory of her dearest day. The day he had plunged a knife millimeters from her vein. And, with her life in his hands, staring into her eyes, had made a different call.
