Yes, I saw it again too. I still feel reasonably convinced by the evidence (as presented in the show) when taken as a whole. Yet, at the same time, I can't resist asking what would have happened if part way through the plagues, the pharaoh would have relented; would the remainder of plagues have occurred anyway (since they were all explained as a logical sequence of events given the environmental circumstances of the time)? If not, why not?
