However, as Manfred attempts to marry Isabella, she escapes to a church with the aid of a peasant named Theodore. Manfred orders Theodore's death while talking to the friar Jerome, who ensured Isabella's safety in the church. When Theodore removes his shirt to be killed, Jerome recognises a marking below his shoulder and identifies Theodore as his own son. Jerome begs for his son's life, but Manfred says Jerome must either give up the princess or his son's life. They are interrupted by a trumpet and the entrance of knights from another kingdom who want to deliver Isabella. This leads the knights and Manfred to race to find Isabella.
