the real da vinci code

did anyone see the program last night on channel 4. it seemed to focus on the fact that there could only be a bloodline between jesus and mary if the priory of sion existed, and that the nights templar had fled to scotland. then again the could still be a bloodline from jesus and mary yet it was just supressed by the church and no secret organisation actually knew. also they left out the part of the extra hand in the last supper painting that doesnt belong to anyone, which would have meant leonardo was trying to show he had put extra things in to it. i thought the program was very informative on the historic aspect of many different things, also there is a blood line from mary and joseph, afterall they had many children so there are people today who would be related to jesus.
