So Jetfire claims that in the beginning there were 7 Primes. Is this to say that in this universe there were 7 Original TFs and not 13? Or, and this is my personal opinion, could there have been 13 original TFs just like the rest of the multiverse, but 7 of them were deemed Primes and charged with leading the TFs?? If so, who might those 7 Primes be? And for that matter, who would have been the other 6 original TFs who were not Primes? Or could it just be that Jetfire was wrong, seeing as how the novel and comic adaptations claim that there are 13, not 7? Maybe we just have yet another difference between the movie and its partner materials (see also: death of Barricade).
