The OP answer is from the very beginning. But in all honesty we apparently do have a weak link in the very first hand off to Linus since there are competing accounts of who was #2. See this CAF Thread :
A compelling non-Catholic argument that gives a very interesting discussion centered on Linus. We never were able to conclude with perfect objectivity that Linus was #2 but the evidence supporting him as #2 is certainly in the realm of highly probable.
