*Warning: this story deals with suicidal thoughts & themes, including a suicide attempt*
Jude and Ingrid come from very different places, down very different roads - though sooner or later, all roads lead to Rome, don't they? In this case, Rome is both of them broken in Berlin, struggling to make sense of their scattered pieces.
They save each other, but on people like them, salvation is wasted, really. And so are they. Wasted, that is.
