Someone should write a fic. Like, respawn is broken, heavy dies leaving Medic nearly defenseless and when he hears the red team incoming, he takes Heavy's shotgun and tears as much ass as possible before getting backstabbed by the spy.
I always imagined the Medic to have a tough exterior that was only broken when one of his team members died, as he felt he had failed them. The addition of the coat over the Heavy shows such respect and care for them even in their death. Again I also imagined him to be willing to die with his team members in battle rather than retreat, there is so much honor and bravery in his eyes. This picture has so much power! I love it!
