There are 2 Thuc lines: Moises Carmona and Gerard des Lauriers. Gerard des Lauriers consecrated in secret(?) and Moises Carmona consecrated openly with supplied jurisdiction. Epikea is mentioned. Bishop Pivarunas was consecrated under Carmona.
When I hear someone saying, oh, the Thuc line is not good or right, I question if they understand there are different Thuc lines.
