 He thinks that the links Pietro had with Berengar II, especially those with Waldrada's father, when he was in exile (see above) initially made an alliance with Otto I unlikely.He points out that Waldrada's father had been hostile to Otto I during his second expedition and had to flee in 962-63 and suggests that Pietro's second marriage might have taken place then, in 962–63, and that it sealed his support to Otto's opponents.He also argues that Otto's mentioned grants were to people Pietro had alienated.
