I suspect the reason for the demand for written communication was to minimize the very 'he said she said' that this little dust up has turned into.  Also written communications would it make it easier when the trail lawyers enter; there would at least be evidence vs what she offers above.

Good call by the Vatican, clearly.

On balance, she offers a rather thin set of counter arguments, with barest of evidence, which can in objective light be read either way.  Thin.
