Well, the chain of events leaves a lot to the imagination of the player,
after the Fireball, she is thrown backwards, MC finds her, with her head resting on the borderstone of the sidewalk (Bordstein in German) seems that she injuried her head there, they could have opened her skull to drain blood or to relive pressure of her skull, surgery often done after car accidents.
and ok this are all facts which I've come up with and which would sound more or less logic, and consitent with the images, if this is like this I don't know the only one who knows is Ceo.
but it sounds plausible, I know this is not enough for your critical thinking, it is just an explanation I've come up with after replaying the sequence.
Good thing this brought the long haired man in the background to my attention,
