I'm just watching this on iPlayer now, has anyone seen it and can clear something up for me?
Is it that his mum never told his dad the truth about his father either and they (son and the dad that brought him up) both found out at the same time? Or did the dad find out at some point before? Did his mother know 100% that her partner was not his biological dad and not tell him or just have an inkling and kept quiet?
I felt it was kind of unclear. I fully understand it's about his search for his father and this isn't all of it but I'm only at the beginning and just trying to get my head around this bit.
