King Gustavo is not idle in the meantime, for he has arranged his men to capture Faramondo when he learns that his enemy is actually in his very palace. Clotilde of course wants Adolfo to prevent this, and when Adolfo acts on her behalf to save her brother, it is scarcely surprising that a truly dreadful confrontation between Adolfo and his father ensues, which ends with Adolfo being imprisoned for treason. Faramondo's attempt to appease Gustavo and ask for Rosimonda's hand in marriage meets with the lack of success one could have anticipated, for Gustavo desires nothing but his enemy's death.
