Bucky already knew he wasn't going to find anything behind that door. That was how she managed to surprise him, forty pounds of kid behind a shiv made out of who-knew-what.
He grabbed her, ignored whatever-it-was sticking out of him. "It's okay, Morgan. It's okay. Your mom sent me."
She kicked, squirmed, tried to bite. He wouldn't have believed him, either.
Into the radio: "Barnes here. I've got her. She's alive."
Potts' voice came over, and Morgan started to cry.
Bucky'd killed her grandparents, watched her dad die. This wasn't absolution...but maybe there was something like grace here anyway.
