I think she was already dead since she says "or do you want to die as well" and the driver doesn't seem to think he hit anyone.So she died saving him there? Her memorial site is at the side of the road which implies she died there.
I think she is another person going through something horrible but unlike him she wants to kill herself. I'm thinking she committed suicide sometime soon where if he spoke to her more he could have saved her thus why its all been suppressed by him. So is my theory.I think she was already dead since she says "or do you want to die as well" and the driver doesn't seem to think he hit anyone.
You fucker you had to remind me lmfaoooPage 9, the hand holding the side of the head panel in the bottom left got me laughing hard. Reminds me of that meme.
