Just for the heck of it, I wonder, if PF were to die before Benedict, whether they might re-elect Benedict as a placeholder for the remainder of his life.
And would he have to take a new regnal number, or would he still stay Benedict XVI?
I guess that'd be his decision, as there is no protocol for such a thing. IOW, it's not like Grover Cleveland having been both the 22nd and 24th presidents. (Or is it?)
