When he breaks into the Avengers Tower he meets Bucky Barnes who feels like it's ironic that he would find another tiny blonde man with horrible self preservation skills to keep safe.

Callie is probably the biggest accident prone, introverted smart ass you'll meet and her tiny world is about to get bigger as she runs into the person who may bring her out of her homebodies shell. as she helps to bring James " Bucky " Barnes out of his shell. Nothing is 100% Cannon it shall be how I want it to be.
