Question: Regarding Paul and Eli. Are they actually twin brothers or is Paul an figment of Eli's imagination and Eli schizophrenic? As far as I remember Paul is only mentioned three times. At the beginning when he meets Daniel, when Eli attacks his father (and says 'you are as stupid as Paul!' and at the end, when Daniel mentions him. Are there any other bits I've missed? Or is it left open to interpretation?
