Fr. Luigi Villa went to Fatima in 1973 and was NOT Allowed to Meet with "Sister Lucy" and was Situated at a Far Distance From "Her" at Mass.
In Father Luigi Villa's visit to Fatima, there is to say that Paul VI, never allowed Fr. Villa to talk with Lucia and the only thing he allowed him was to attend a Mass where Lucia was present, but very far away from Fr. Villa.
So, he could not find anything about the replacement of Sister Lucia.
