I think I heard her say in an interview that Ratzinger (this is before his election) does not truly believe in the prophecies of Fatima. This may be the reason why she doesn't seem to be happy about the situation.
For whatever reason Ratzinger had for suppressing the Fatima secret, he may reap the consequences as the prophecied bishop in white who flees Rome and dies a cruel death. It would be a strange, sad twist of fate.
